In this study, the tensile strength and fracture mechanisms of Al6061-T6 plate specimens
were evaluated based on von Mises stress and triaxial tensile stress according to the …

The compressive strength is very important for petroleum and other engineering studies.
However, the effect of pore size and fluid distribution on the rock's strength is not fully …

It is worthy to investigate how it will affect the parameters calibration using an average stress
state variable before the practical application of a ductile fracture criterion. In order to study …

This research aims to correlate the macroscopic fracture phenomenon with its microscopic
fracture mechanism for an advanced high-strength steel (AHSS) TRIP 780 sheet by applying …

Hydraulic fracturing-induced microseismicity has drawn public attention in recent years.
However, understanding the behavior of hydraulic fracture is limited due to the complex …

A new fracture model is developed to predict the ductile fracture of structural steel under
multiaxial stress states. First, the Lee–Mear void growth theory is used to establish the …

Fracture often occurs in the spin forming process of thin-walled metal sheets, due to the
limited fracture strain and local large plastic deformation of the sheets during the process …

A phenomenological ductile fracture model is proposed by a careful consideration of void
nucleation, growth and coalescence during plastic deformation. Within the model framework …

In this paper, the microstructural damage evolution of a steel with a ferrite–pearlite
microstructure (C45E) was investigated during the process of cold upsetting. The …
