Influence of flaw inclination angle and loading condition on crack initiation and propagation
TL;DR: In this article, the influence of pre-existing flaw inclination angle on the cracking process was analyzed by means of finite element method (FEM) and non-linear dynamics method, and the resultant crack types, crack initiation sequences and the overall crack pattern were different under different loading conditions.

Numerical simulation of dynamic fracture of concrete through uniaxial tension and L-specimen
TL;DR: In this paper, the authors numerically evaluated the dynamic fracture of concrete using uniaxial tension and L-specimen and found that the direction of crack propagation strongly depends on displacement rate.

Numerical study of dynamic behavior of concrete by meso-scale particle element modeling
Chuan Qin,Chuhan Zhang +1 more
TL;DR: Based on the Particle Element Method, a meso-scale dynamic model is developed for numerical study of the dynamic failure behavior of three-phase concrete i.e., aggregate, mortar, and interface, under different strain rates as mentioned in this paper.

Continuous damage model for load-response estimation of concrete
TL;DR: In this paper, the authors estimate the stress-strain relationship for concrete in uniaxial tension by means of a semi-empirical damage model, which is a measure of the relative portion of pores and cracks in the material.

Elastostatic problems of curvilinear cracks in bonded dissimilar materials
A.B. Perlman,G.C. Sih +1 more
TL;DR: In this article, the problem of finding the crack-tip stress-intensity factors, employed m the Griffith-Irwin theory of fracture, was solved in closed form by applying the complex function theory dealing with sectionally holomorphic functions.
