Semi-flexible pavement has been widely used in China's road construction due to its excellent rutting resistance. Due the large difference volume stability between matrix asphalt mixture and cement mortar, internal stress of semi-flexible material is concentrated cracking likely occur. To explore influence different Influencing factors on resistance materials. This paper orthogonal design metho...

In this paper we study numerically and experimentally non-reversible deformation of anisotropic, semi-flexible fibre networks. We formulate a Discrete Element Model (DEM) with bonded particles to simulate uniaxial compression such networks use model describe quantify the effect elasto-plastic contacts fibre-fibre adhesion on deformation. Our results show that inter-fibre plays role for in low s...

Abstract The description of the cyclic mobility observed prior to liquefaction in geomaterials requires sophisticated constitutive formulation describe plastic deformation induced during loading with small stress amplitude inside yield surface. This requirement is realized subloading surface model , which enclosing a purely elastic domain not assumed, while assumed other elastoplasticity models...

A phase field model for anisotropic, elastoplastic fracture in layered structures obtained by 3D printing processes is proposed. An extension of anisotropic to elastoplasticity developed. The able describe a transition from quasi-brittle behaviors depending on the angle layers microstructure with respect external loading. Such feature special interest behavior printed materials. present introdu...

This work is devoted to anisotropic continuum-damage mechanics in the quasi-static, isothermal, small-strain setting. We propose a framework for damage evolution based on compliance tensor as primary variable, context of generalized standard models dissipative solids. Based observation that Hookean strain energy density linear elasticity jointly convex and tensor, we design thermodynamically co...

A new energy-dissipation-based rate-independent constitutive law within the framework of elastoplasticity coupled with damage is proposed. With this methodology, inelastic strains and stiffness degradation exhibited by quasi-brittle materials under monotonic or cyclic loading conditions are taken into account. The proposed model able to capture micro-cracks closure-reopening effects due load re...
