Two procedures (direct differentiation and adjoint structure) for design sensitivity analysis of
nonlinear structural systems with path dependent effects are described in this paper …

Large deformation finite element (LDFE) analysis is being applied increasingly in
geomechanics as it allows numerical interpretation of problems in which the structural …

This paper presents a new geometric nonlinear formulation for static problems involving
space trusses. Based on the finite element method (FEM), the proposed formulation uses …

This paper investigates the applicability and accuracy of existing formulation methods in
general purpose finite element programs to the finite strain deformation problems. The basic …

In this paper an incremental approach is used to derive an arbitrarily-Lagrangian-Eulerian
(ALE) finite element formulation including a complete expression of the external virtual work …

Adopting an updated Lagrange approach, the general framework for the fully non‐linear
analysis of curved shells is developed using a simple quadrilateral C0 model (HMSH5). The …

Some aspects of engineering dynamics, such as nonlinearities and transient motion of many
interconnected parts, remain difficult to handle today. To comply with increasing demands …

In this paper, a solution method is presented for the analysis of contact/impact between
deformable bodies. The method is different from Lagrange multipliers and Penalty methods …

The paper presents a finite element (FE) procedure for solving contact thermoelastoplastic
problems at large strains. A rigorous derivation of the constitutive relations used and the …

This paper focus on the treating the multi freedom constraints in geometrically nonlinear
buckling and post buckling analysis of truss structure using finite element method. The …
