Damage models, particularly the Gurson–Tvergaard–Needleman (GTN) model, are widely
used in numerical simulation of material deformations. Each damage model has some …

Predicting the ductile fracture in aluminum alloys during hot deformation is important for
controlling product quality. To this end, this paper proposes an improved damage-coupled …

Nonlinear matrices employed in asphalt-based composites exhibit a prominent nonlinear
elastic-viscoplastic-viscodamageable mechanical response. The constitutive model for this …

Polyurethane foam (PUF) is a popular insulation material and has crucial mechanical
characteristics under compression in the principal loading direction, including nonlinear …

The article gives an overview and analysis of the models of the damage accumulation in
monolithic materials when exposed to prolonged and repeatedly applied load. The …

The geometric size effects (GSEs) of Lemaitre damage model parameters (the critical
damage value at rupture, D c, the strain at the damage threshold, ɛ D, and the strain at …

The superposition effect of various cutting mechanisms (CM) in the fine drilling process
brings great challenges to the accurate characterization of the cutting stress field of the …

Application of optimization techniques to the identification of inelastic material parameters
has substantially increased in recent years. The complex stress–strain paths and high …

Water-bearing fractured rock masses are prone to geological hazards due to freeze–thaw
(FT) damage, which brings adverse effects on the stability of rock engineering. In order to …

This paper presents the numerical and experimental investigation of the incremental sheet
forming (ISF) process with the Lemaitre damage model to incrementally form parts of conical …
