Analysis of Open-Hole Compressive CFRP Laminates at Various Temperatures Based on a Multiscale Strategy
TL;DR: In this article, a multiscale analysis strategy was proposed to analyze the failure behaviors of open-hole compressive (OHC) CFRP laminates, where micro-level intralaminar failure was defined in fiber and matrix components with a modified micromechanics failure theory.

TL;DR: In this article, a sensitivity analysis on delamination position and size has been carried out on a C/C-SiC body flap for a reusable re-entry vehicle, with embedded circular delamination, comparing the delamination onset stress level with respect to the stress state corresponding to the most critical body flap service load.

Fracture analysis of woven textile composite using cohesive zone modeling
TL;DR: In this paper, the fracture behavior of plain weave textile composite was studied numerically by finite element analysis and cohesive zone modeling, which provided the detailed fracture initiation and propagation history explicitly with complicated fracture modes.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: 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.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.

Fracture and Size Effect in Concrete and Other Quasibrittle Materials
Zdeněk P. Bažant,Jaime Planas +1 more
TL;DR: In this paper, the authors used the Weibull-type approach to measure the effect of size effect on structural strength of a crack and its size effect in terms of the number of cracks and the size of the cracks.
