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:

Fundamental physical principles and cohesive zone models at finite displacements - Limitations and possibilities
TL;DR: In this paper, a new elasto-plastic model is proposed which fulfills all requirements provided by thermodynamic consistency, balance of angular momentum and material frame indifference, and it is shown that among the existing prototype cohesive zone models within the classical cohesive zone framework, only fully isotropic elastic models or fully-isotropic elastic models combined with isotropical damage theory fulfill all of the aforementioned fundamental principles whereas present elastosplastic models do not.

Macro-performance evaluation of friction stir welded automotive tailor-welded blank sheets: Part II – Formability
Dae Yong Kim,Wonoh Lee,Junehyung Kim,Kyung-Hwan Chung,Chongmin Kim,Kazutaka Okamoto,Robert H. Wagoner,Kwansoo Chung +7 more
TL;DR: In this article, Chung et al. investigated the formability of automotive friction stir welded TWB (tailor-welded blank) sheets in three applications including the simple tension test with various weld line directions, hemisphere dome stretching and cylindrical cup drawing tests.

Analysis of Test Specimens for Cohesive Near-Bond Failure of Fiber-Reinforced Polymer-Plated Concrete
TL;DR: In this paper, the authors investigated and compared two bond failure tests: a simplified test (or simple shear test) and a recently proposed shear/normal test, and discussed the characteristics of both tests and how they relate to the midspan debonding and end peeling failures.

Determination of Young’s modulus, fracture energy and tensile strength of refractories by inverse estimation of a wedge splitting procedure
TL;DR: In this article, the authors used the Tschegg wedge splitting test to characterize the fracture behavior of ordinary ceramic refractory materials and found that Young's modulus is accurately identified as well as the tensile strength and total specific fracture energy when a trilinear strain softening law is employed.

Thermodynamic Consequences of Strain Softening in Tension
TL;DR: In this article, the authors analyzed the strain softening behavior of a tension bar loaded by an increasing elongation and showed that the softening region cannot be considered to have a specific strain state, but rather is described by strrss-elongation relation.
