Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TLDR
In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.About:

Three Dimensional Cohesive-Element Analysis and Experiments of Dynamic Fracture in C300 Steel
TL;DR: In this article, coherent gradient sensing (CGS) has been used to study dynamic fracture in C300 maraging steel, where the specimens were subjected to three-point bend impact loading under a drop weight tower and high speed photographs of the CGS interferograms were analyzed to determine the crack tip location, the velocity and the dynamic fracture toughness as a function of time.

A method for 3-D hydraulic fracturing simulation
TL;DR: In this article, the authors present a method for the simulation of 3D hydraulic fracturing in fully saturated porous media, where the discrete fracture(s) are driven by the fluid pressure.
Journal ArticleDOI
The fracture toughness of soft tissues
TL;DR: The conclusion is that, in most cases, fracture toughness has not in fact been measured for porcine muscle tissue, and a useful finding is that soft tissues are highly tolerant of defects, able to withstand the presence of cracks several millimetres in length without significant loss of strength.

3D Crack propagation in unreinforced concrete. A two-step algorithm for tracking 3D crack paths
TL;DR: In this article, the authors introduce a cohesive fracture process zone, which is characterized by a transversely isotropic traction-separation law and combine the cohesive crack concept with the partition of unity finite element method, where the finite element space is enhanced by the Heaviside function.

Nonlinear mechanical behaviour and analysis of wood and fibre materials
TL;DR: In this article, the mechanical properties of the cellular structure of wood are characterized and modelled, the irregular cell shape, the anisotropic layered structure of the cell walls and the periodic variations in density being taken into account.
