Abstract:
A method of analysis for three-dimensional reinforced concrete
thin-walled beams and frames based upon the finite element
displacement formulation is presented. A stiffness matrix for the
analysis of thin-walled beams with an arbitrary open cross-section
consisting of longitudinal filaments to represent the concrete and
reinforcing steel is derived. The description of the element is based
on the assumptions introduced by V.Z. Vlasov, and a method of
describing the warping of a cross-section, which is valid for both
straight and curved members with either open or closed
cross-sections. An updated Lagrangian formulation is used to take
into account the material nonlinearities and the effects of changing
structural geometry. (21 refs.) Keywords: Beams

Abstract:
A proposed modification of an arch dam was subjected to parallel
linear and nonlinear static analysis using ADINA 84. The load path
selected for comparison produced high tensile stresses in the linear
model and therefore significant cracking in ADINA's concrete model.
The analysis clearly shows the ability of the arch dam to
redistribute the loads after extensive cracking has occurred. (3

element analysis of temperatures and stresses in a single-pass
butt-welded pipe - influence of mesh density and material modelling

Abstract:
Single-pass girth butt welding of a carbon-manganese pipe is studied
numerically using the finite element codes ADINAT/ADINA. This model
is used to investigate the influence on the residual stress state of
pipe geometry, mesh density and material modelling. Results are
compared with previous results from two different FE analyses and an
experimental investigation. One of the FE analyses was fully three
dimensional and the other employed shell elements. The calculated
residual stresses were found to differ significantly only when
different material models were employed. The thermal strain seemed to
be the material parameter with the largest influence on the residual
stress state. Especially the changes in thermal strain during phase
transformations seemed to have a great influence. Almost the same
residual stresses were obtained for two pipes with different pipe
geometries and weld parameters. (23 refs.) Keywords: Pipe

Abstract:
The design of direct mount chip attach systems requires proper
balancing of two design issues to ensure a satisfactory system: (i)
adequate cooling of the electronic chip assemblies, and (ii) thermal
expansion match between the chip assemblies and the substrate to
ensure structural integrity during operation. Techniques using the
ADINA-T thermal analysis program which have been found to provide
suitable thermal modeling of direct chip attach systems are
discussed. Correlation between model and experimental data is
provided, and guidance on which direct mount systems can be
adequately modeled is described. Several studies of direct chip mount
systems are detailed, and examples of the evaluations which can be
performed using ADINA-T are discussed. Finally, the technology
required to extend the range of electronic systems which can be
effectively modeled is discussed. (3 refs.)

Abstract:
This paper presents the development of a structural design
optimization methodology and a software system DESIGN-OPT by
integrating numerical optimization techniques, finite element
methods, and pre- and post-processing CAE tools. Specifically, the
commercially available codes COPES/ADS and ADINA are employed for
numerical optimization and finite element analysis, respectively; and
software packages like MOVIE.BYU, PLOT10 and SUPERTAB are used for
pre- and post-processing purposes. The finite-difference and
semi-analytical (or implicit differentiation) approaches of design
sensitivity analysis were explored with the ADINA code for static as
well as dynamic problems; and a comparison of the two approaches is
made in terms of computational efficiency, solution accuracy and the
ease of software implementation. A broad range of element types
(truss, beam, plate and 2D/3D continuum) are considered. Additional
aspects of the subject are discussed. (21 refs.)

Automatic
load incrementation for rubber-like bodies in contact

Abstract:
The authors propose and study an algorithm for automatic load
incrementation, suitable for general path-dependent problems with
nonproportional loading and frictional contact phenomena. The load
steps are chosen adaptively on the basis of the iteration history and
the occurrence of special events, such as contact (material overlap).
Automatic restart is made at the indication of the beginning of
divergence or overlap. At overlap restart is made from the latest
converged solution with a step chosen to reach a configuration
immediately before contact, from which the analysis then proceeds
with a strongly reduced step. The applicability of the algorithm is
demonstrated on typical problems involving highly nonlinear rubber
structures. (15 refs.) Keywords: Structural

Abstract:
A valuable approach for the automatic generation of effective finite
element meshes is presented. The approach comprises, firstly, an
initial mesh construction and, secondly, an h-version of adaptive
refinement based on an error analysis. For the initial mesh
construction, a robust triangulation scheme for 2D analysis and
tetrahedronization scheme for 3D analysis are used, in which the
elements are generated from the outside boundaries. For the adaptive
refinement process, an error indicator is used with a relaxation
factor to obtain efficient solutions. The initial mesh construction
schemes have been implemented for 2D and 3D analyses whereas the
self-adaptive mesh improvement procedure has only been implemented
for 2D analysis. Example solutions are given to demonstrate the
solution procedures. (20 refs.) Keywords: Mathematical

Abstract:
Two damage models were implemented into the finite element program
ADINA to study the correlation between microscopical damage and
macroscopical material failure. In the first model, based on the
Gurson yield function the nucleation, growth and the coalescence of
voids were incorporated into the constitutive relations. In the
second model the void growth was determined according to the Rice and
Tracey model using the von Mises yield function, and material failure
was simulated by eliminating the elements where the critical void
growth ratio was exceeded. The numerical results for the local and
global behaviour of the specimens were compared with experiments. The
generality of the damage parameters was checked by investigating
several specimen geometries. Both damage models deliver qualitatively
consistent results with regard to the influence of the stress
triaxiality on the void growth and on the beginning of the material
failure. However, the Gurson model gives a more accurate numerical
simulation because the damage development and the stress drop
continue after the onset of void coalescence while the critical void
growth model causes less convergence problems in the simulation of
large crack extension. The J<sub]R</sub]-curve
was estimated on the basis of both models. (15 refs.)

Abstract:
A dynamic elasto-plastic large displacement response analysis of the
underside of a generic vehicle floor model to empirically obtained
triangular overpressure loading has been conducted using
three-dimensional shell elements in conjunction with the ADINA
nonlinear finite element analysis code. Although several simplifying
assumptions and approximations are applied to generate the basic
floor model and the forcing function, the investigation provides
valuable insight into the response behavior of vehicle bottom floors
to externally applied overpressure loads and an inexpensive
nondestructive method of evaluation of the vulnerability of army
vehicles subject to transient loads which are spatially varying. (17

Abstract:
In this study, the problem of a rectangular block, fixed over a face
and in contact with a frictional flat surface on the opposite face,
is considered. The rubber is modeled as the Mooney-Rivlin type of
material. The effect of bulk modulus on the stiffness of the block is
first investigated. The normal and the tangential forces are
calculated for a wide range of coefficients of friction and the
stick-slip phenomenon is predicted as a function of coefficient of
friction. The loading conditions considered are compression of the
block with normal force and the loading of the block with both normal
and tangential displacements. The qualitative wear resistance
features of the block are explored by the work density of the
frictional contact forces in the loading process. (3 refs.)
