Fast Nodal Hessian Computation for Peridynamic Fracture Simulation

Computer Graphics Forum, EarlyView.
A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

A 3D contact investigation of rough surfaces considering elastoplasticity

Exacta, 2009
In this work, the non-penetration condition and the interface models for contact, taking into account the surface microstructure, are investigated in detail. It is done using a homogenization procedures presented by Bandeira, Wriggers and Pimenta (2001a),

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Airy Stress Function-Based Elastoplastic Analysis of Plates with Holes Using the Nonconforming Morley Finite Element Method

Applied Sciences
This paper presents a stress-function-based finite element formulation for two-dimensional elastoplastic plane-stress problems with holes. The Airy stress function is used as the primary global unknown, and the resulting non-homogeneous biharmonic ...

Isogeometric analysis of linear isotropic and kinematic hardening elastoplasticity

Vietnam Journal of Mechanics, 2017
Material nonlinearity is of great importance in many engineering problems. In this paper, we exploit NURBS-based isogeometric approach in solving materially nonlinear problems, i.e. elastoplastic problems.

Sublimation inside an Elastoplastic Material

Physical Review Letters, 2008
Thermodynamic and kinetic approaches for sublimation inside elastoplastic material under tensile stress are developed for large strains. Various conceptual problems related to irreversible plastic deformation are addressed for a spherical bubble. They include definitions of the thermodynamic driving forces and activation energies, nontraditional ...

Performance of a Mixed Least‐Squares Finite Element Formulation With Application in Poroelasticity

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT A mixed least‐squares finite element method (LSFEM), previously proposed for the theory of porous media (TPM), is further investigated in this work. Finite deformation of a fully saturated, incompressible solid–fluid binary system is studied using the LSFEM.

Micropolar elastoplasticity and its role in localization

, 1993
In this article we focus on micropolar elastoplasticity and the conditions for the formation of spatial discontinuities. After a brief review of micropolar kinematics and balance equations, an augmented localization tensor is developed for elastoplastic ...

Closed system of coupling effects in generalized thermo-elastoplasticity

International Journal of Applied Mechanics and Engineering, 2016
In this paper, the field equations of the generalized coupled thermoplasticity theory are derived using the postulates of classical thermodynamics of irreversible processses. Using the Legendre transformations two new thermodynamics potentials P and S

Strain‐Space Hyperreduction Using Empirically Corrected Cluster Cubature With Linear and Quadratic Approximation Spaces

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Strain‐space reduced cubature techniques such as the Empirically Corrected Cluster Cubature (E3C) considerably reduce the integration effort incurred in computational homogenisation problems. In this work, we apply E3C in tandem with projection‐based model reduction techniques utilising both linear and quadratic approximation spaces.
