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:

Response of ultra-high-performance fiber-reinforced concrete beams with continuous steel reinforcement subjected to low-velocity impact loading
TL;DR: In this article, the effect of reinforcement ratio on the flexural behavior of ultra-high-performance fiber-reinforced concrete (UHPFRC) beams under impact loading was investigated.

Nonlinear fracture of cohesive materials
Jaime Planas,Manuel Elices +1 more
TL;DR: In this article, the effect of the size and shape of the softening curve on the value at the peak load of several variables for three point bent notched beams was analyzed for very large specimen sizes.

Experimental characterization and numerical simulations of a syntactic foam/glass fibre composite sandwich
TL;DR: In this paper, the main results of an experimental and numerical investigation on the mechanical behaviour of a composite sandwich primarily designed for naval engineering applications are presented; the skeleton of the sandwich is made of glass-fibre/polymer-matrix composites; their interior layers are connected with interwoven threads called piles which cross the sandwich core.

Strain rate effects on dynamic fracture and strength
David E. Lambert,C. Allen Ross +1 more
TL;DR: In this article, an experimental procedure and accompanying theoretical analysis is presented to produce a well-characterized technique for quantifying dynamic fracture properties of quasi-brittle materials, and the results show that the effective fracture toughness and specimen strength both increase significantly with loading rate.
Journal ArticleDOI
Hyperelasticity with softening for modeling materials failure
TL;DR: In this article, the authors introduce a limiter for the strain energy, the critical failure energy, which can be interpreted as a failure constant characterizing the material "toughness".
