A coupled thermal-elastic-plastic-damage model for concrete subjected to dynamic loading
is proposed. This model is formulated in the thermodynamic framework, with the adoption of …

A novel three-dimensional (3D) fractional plastic flow rule that is not limited by the
coordinate basis of the differentiable function is proposed based on the fractional derivative …

This paper develops a modeling method with an incremental stress–strain–environment
constitutive model to predict the change in the plastic mechanical behavior of concrete …

Particle shape has a significant effect on the shear strength and shear dilatancy properties of
granular materials. This study presents a granular thermodynamic theory investigate the …

The core mission to establish elastoplastic constitutive model is how to determine the
magnitude and direction of plastic strain increment for material under the given load …

To capture the uniaxial compression fracture of concrete composite is still a great
challenging problem. To this end, the newly proposed nonlocal macro–meso-scale …

Particle breakage could significantly influence the shear strength, volumetric deformation,
stress–dilatancy relationship, and plastic-flow rule of crushable sands. A breakage …

The seismic failure mechanism of underground structures presents that the insufficient
lateral deformation capacity of central columns will result in the collapse of the overall …

The diffuse damage and localized cracking of quasi-brittle materials (ie, rocks and
concretes) under compression can be delineated by a matrix-microcrack system, wherein a …

Based on viscoelastic peridynamic method, a numerical model of a three-point bending
concrete beam with an initial crack is established in this work, whose accuracy and …
