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:

Smeared cracking, plasticity, creep, and thermal loading—A unified approach
TL;DR: In this paper, a recently proposed smeared crack model which properly handles nonorthogonal cracks is further elaborated, and it is proved that the model obeys the principle of material frame-indifference.

Analytical Model for Fictitious Crack Propagation in Concrete Beams
TL;DR: In this article, an analytical model for load-displacement curves of concrete beams is presented, where the fracture is modeled by a fictitious crack in an elastic layer around the midsection of the beam.
Journal ArticleDOI
A modified damage model for advanced high strength steel sheets
TL;DR: In this paper, a simple tension test was performed to determine anisotropic properties and strain rate sensitivities, and an inverse calibration method based on a damage model utilizing a triaxiality-dependent fracture criterion and hardening behavior with stiffness deterioration was developed.

Size Effect on Compressive Strength of Plain and Spirally Reinforced Concrete Cylinders
TL;DR: In this paper, the fracture mechanics type size effect on the compressive strength of cylindrical concrete specimens was studied, with the diameter, the height/diameter ratio, and the volumetric spiral ratio of the cylinder considered as the main parameters.

Probabilistic nonlocal theory for quasibrittle fracture initiation and size effect. i: theory
Zdenek P. Bazant,Drahomír Novák +1 more
TL;DR: In this article, a nonlocal generalization of Weibull theory for structures that are either notched or fail only after the formation of a large crack is extended to predict the probability of failure of unnotched structures that reach the maximum load before a large fracture forms, as is typical of the test of modulus of rupture.
