Tension-compression asymmetry based on different energy decompositions within a gradient-extended two-surface damage-plasticity framework Open
The present study employs and investigates in detail several energy decompositions to capture the tension-compression asymmetric damage behavior of ductile materials based on a gradient-extended two-surface damage-plasticity framework. A s…

Topology optimization with a finite strain nonlocal damage model using the continuous adjoint method Open
This study presents a unified formulation of topology optimization with a finite strain nonlocal damage model using the continuous adjoint method. For the primal problem to describe the material response including deterioration, we conside…

Diffusive-discrete crack transition without remeshing achieved by extended B-spline-based implicit material point method Open
A novel procedure is proposed to realize a transition from a diffusive to discrete crack topology with the help of extended B-spline (EBS) basis functions in the implicit material point method. The crack initiation and propagation are dete…

Crack phase‐field enhanced finite cover method for dynamic fracture at finite strain Open
Summary This study presents an enhancement of the diffusive‐discrete crack transition scheme (10.1002/nme.7169) to describe dynamic fracture at finite strain. In the enhanced scheme, the crack initiation, propagation, and bifurcation proce…

Extended B‐spline‐based implicit material point method enhanced by F‐bar projection method to suppress pressure oscillation Open
Summary An enhancement of the extended B‐spline‐based implicit material point method (EBS‐MPM) is developed to avoid pressure oscillation and volumetric locking. The EBS‐MPM is a stable implicit MPM that enables the imposition of arbitrary…

Gradient damage model for ductile fracture introducing degradation of damage hardening modulus: implementation and experimental investigations Open
This study presents a gradient damage model for ductile fracture, in which the damage hardening modulus is degraded by the accumulation of plastic deformation and the volume expansion caused by negative hydrostatic pressure. The proposed m…
