Thermal shock resistance analysis of cracked nanoplate with embedded elliptical defect via nonlocal differential elasticity theory

Investigation of free vibration of multi-cracked nonlocal nanobeams

This paper investigates the free transverse vibration characteristics of nanobeams containing multiple cracks using the Euler–Bernoulli beam framework augmented by Eringen’s nonlocal elasticity theory. A size-dependent model is formulated by introducing discontinuities in slope and transverse displacement at cracked se...

A phase field model for thermoelastic fracture in hyperelastic solids under finite deformation

This paper develops a phase field model for simulating crack propagation in hyperelastic solids subjected to coupled thermo-mechanical loading under finite deformation. The model integrates the Neo-Hookean constitutive law with a thermodynamically consistent framework that captures key multiphysics couplings: finite th...

Numerical study on geometric constraint effects on ductile fracture toughness of thin advanced high-strength steel sheet

The total fracture energy arises from the energy dissipated within the fracture process zone, comprising the work of necking and the work of fracture, and the energy dissipated in the surrounding plastic zone, referred to as plastic work. The essential work of fracture methodology expresses the fracture toughness in te...

Peridynamic differential operator for transient thermoelastic responses of laminated structures with interface cracks and thermal resistance

Laminated structures are widely used in thermal-shock environments, where material-property mismatch, interfacial thermal resistance, and delamination may cause discontinuous temperature and stress fields. In this study, a dual-phase-lag (DPL) generalized thermoelastic model is established within the framework of the p...

Constitutive modeling of concrete under tensile loading: damage evolution from 3D microcracks

MIXED-MODE CRACK PROPAGATION ANALYSIS IN ORTHOTROPIC PLATES WITH CENTRAL AND HOLE-EDGE CRACKS UNDER TENSILE LOADING

The inhomogeneity and anisotropy in orthotropic bodies make their analysis and damage mechanisms more important and complex. To simplify the analysis and facilitate numerical implementation, we assume that the material is homogeneous. This assumption allows us to use classical analytical models while maintaining a cons...
