A perforation model is developed to predict the attitude deflection in the oblique perforation of concrete targets by a rigid projectile, in which the inertial moment of the projectile is introduced, together with taking the attitude deflection durin

Considering the self-similar characteristic of irregular pore network of materials during the damage evolution process, a pore ubiquitiform model (PUM) is developed to characterize the multiscale pore or microcrack network of quasi-brittle materials,

In recent decades, the incubation time has become a critical parameter to study dynamic failures for materials, but its underlying physical meaning is still vague and the corresponding model remains lacking. In this study, we first established a theo

Based on the concept of ubiquitiform, a ubiquitiformal crack extension model is developed for quasi-brittle materials. Numerical simulations are carried out using the ABAQUS software with the XFEM-based cohesive segments method to determine the ubiqu

In this study, two general solutions for the dynamic tensile load-carrying capacity of brittle materials subject to an arbitrary incident stress wave in the form of Fourier integrals are derived. In order to verify the general solutions, we reduce th
