The primary objective of this manuscript is studying the effect of T-stress term (T) on the crack propagation angle (CPA) and fracture toughness of in-plane mixed mode loading by utilizing a generalized form of minimum strain energy density (SED) cri

The values of mode II fracture toughness reported in the literature for several rocks are studied theoretically by using a modified criterion based on strain energy density averaged over a control volume around the crack tip. The modified criterion t

A modified energy-based model called the generalized averaged strain energy density (ASED) criterion is proposed to predict the mixed mode I/II fracture resistance of brittle and quasi-brittle materials. The proposed criterion takes into account the

In this paper, the meshless local PetrovGalerkin (MLPG) method is used for three-dimensional (3D) elastodynamic analysis of functionally graded (FG) isotropic plates. The 3D linear elasticity theory and infinitesimal strains are the basic assumptions

In this paper the minimum strain energy density criterion is modified to predict the values of mode II fracture toughness reported in the literature for several brittle and quasi-brittle materials. The experimental results are all related to mode II

The effects of specimen geometry on the fatigue crack growth rate and the number of elapsed cycles have been investigated experimentally and theoretically for Al 7075-T6 using four different cracked specimens with positive and negative T-stresses. Al

The aim of this paper is to study the effects of specimen geometry on fatigue crack growth rate and fatigue life in cracked components by using a modified form of averaged strain energy density criterion. The modified criterion takes into account the

In this paper, a modified mixed mode fracture model called the generalized strain energy density criterion is proposed. The criterion uses three key crack parameters including: the mode I and mode II stress intensity factors (KI and KII) and the T-st

Mode-I fracture strength and crack growth trajectory of polymethylmethacrylate (PMMA) samples have been investigated experimentally and theoretically for five different cracked specimens. Although all the specimens have been tested under pure mode I
