red sandstone was tested in the freeze-thaw cycle under open and saturated conditions, and the mechanical properties of samples after different freeze-thaw cycles (0, 5, 10, 20, and 40 freeze-thaw cycles) were tested under the four kinds of confining ...

A 3D non-orthogonal plastic damage model for concrete
, 2020A plastic damage model with the non-orthogonal flow rule is developed, which is consisted of the damage part driven by plastic strain and the plastic part based on effective stress.

A variationally consistent phase-field anisotropic damage model for fracture
, 2020In the phase-field modeling of fracture in brittle and quasi-brittle solids, it is crucial to represent the asymmetric tensile/compressive material behavior. Existing phase-field models generally adopt either an intuitive split of the free energy density

A length scale insensitive phase-field damage model for brittle fracture
Journal of the mechanics and physics of solids, 2018Being able to model complex nucleation, propagation, branching and merging of cracks in solids within a unified framework, the classical phase-field models for brittle fracture fail in predicting length scale independent global responses for a solid ...

A novel mesoscopic progressive damage model for 3D angle-interlock woven composites
, 2020In this paper, a novel mesoscopic progressive damage model is proposed to investigate the effective properties and damage mechanisms of 3D angle-interlock woven composites. The damage activation is based on the three-dimensional version of Puck criterion.

A multiscale elasto-plastic damage model for the nonlinear behavior of 3D braided composites
Composites Science And Technology, 2019A multiscale elasto-plastic damage model is developed to predict the nonlinear behavior of three-dimensional (3D) braided composites. In this model, the sequential multiscale method is applied to transfer the effective properties from microscale to ...

Composite structures, 2019
In this paper, a 3D finite element model is established in ABAQUS/Explicit based on a modified progressive damage model to study the dynamic mechanical response and damage development in cross-ply composite laminates subjected to low-velocity impact. The
