Rigorous derivation of a plate theory in linear elastoplasticity via Γ-convergence

open access: yes, 2011
This paper deals with dimension reduction in linearized elastoplasticity in the rate-independent case. The reference configuration of the elastoplastic body is given by a two-dimensional middle surface and a small but positive thickness.

Dynamic Analysis of Electrically Assisted Turbocharger Rotor Considering Contact Effects in Nut Structures

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The rotor system of an electrically assisted turbocharger (EAT) is composed of multiple shaft components; The nonlinear connection and contact effects make it difficult to determine the system dynamic characteristics. To improve the modeling accuracy of EAT rotor system and evaluate the influence of contact between multi‐axis components and ...

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Hypoplastic Model for Unsaturated Soils With Degree of Saturation Dependent Stiffness

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper presents an enhanced hydro‐mechanically coupled hypoplastic constitutive model for unsaturated soils, developed by extending an existing framework, with particular emphasis on improving the stiffness formulation to better capture the influence of the degree of saturation. The existing framework links Bishop's effective stress to the

Certain remarks on a class of evolution quasi-variational inequalities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We prove two existence theorems, one for evolution quasi-variational inequalities and the other for a time-dependent quasi-variational inequality modeling the quasi-static problem of elastoplasticity with combined kinetic-isotropic hardening.

Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

open access: yesPolymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

open access: yesSmall Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

A wavelet-Galerkin method for elastoplasticity problems

open access: yes, 1999
We use biorthogonal B-spline wavelet bases to discretize the dynamic response problem for a straight elasto-plastic rod. In an elastic predictor/plastic corrector method, we use interpolatory wavelets for the stress correction.
