Phase-field crack approximation relies on the proper definition of the crack driving strain energy density to govern the crack evolution and a realistic model for the modified stresses on the crack surface. A novel approach, the directional split …

This paper presents a numerical method to simulate a Gaussian random field over a 3D surface whereas the existing methods in the literature are limited to simple 2D surfaces. This new approach is summarized in the following. First, a covariance …

A novel approach based on dynamic thermal vibration is proposed to calculate the heat capacity and thermal expansion coefficient (TEC) for metal crystalline materials from 0 K to the melting point. The motion of metal atomic clusters is decomposed …

The construction of a homogeneous medium equivalent to a heterogeneous one under quasi-brittle fracture is investigated in the case of non-separated scales. At the microscale, the phase field method to fracture is employed. At the scale of the …

An integrated computational framework is presented for the automated modeling and simulation of the failure response of carbon fiber reinforced polymers (CFRPs) with arbitrary-shaped, randomly-misaligned, embedded fibers. The proposed approach …
