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:

A discrete strong discontinuity approach
TL;DR: In this paper, strong discontinuities are embedded in finite elements to describe fracture in quasi-brittle materials and the displacement jumps are transferred to the element nodes as a rigid body motion.

Predicting the post-cracking behavior of normal- and high-strength steel-fiber-reinforced concrete beams
TL;DR: In this article, a grant (13SCIPA01) from Smart Civil Infrastructure Research Program funded by Ministry of Land, Infrastructure and Transport (MOLIT) of Korea government and Korea Agency for Infrastructure Technology Advancement (KAIA).

A scale-invariant cohesive crack model for quasi-brittle materials
TL;DR: In this paper, a scale-independent fractal cohesive law is proposed to obtain a unique constitutive relationship for softening in concrete, which can be used to extrapolate results from small laboratory specimens to full-scale structures.

Mechanical properties of open-cell rhombic dodecahedron titanium alloy lattice structure manufactured using electron beam melting under dynamic loading
TL;DR: In this article, the compressive behavior of Ti-6Al-4V lattice structures with rhombic dodecahedron unit cells is investigated at four different strain rates, and the peak stress exhibits a certain dependence on the loading rate for the structures with smaller unit cells.

Seismic fracture analysis of concrete gravity dams based on nonlinear fracture mechanics
TL;DR: In this article, a numerical scheme based on nonlinear crack band theory is presented to study the 2D seismic fracture behavior of concrete gravity dams, where a mesh size close to the characteristic size of the crack band of concrete material is adopted, so that the strain softening behaviour of the concrete can be properly taken into account.
