TL;DR: In this paper, two simple opening-mode finite strip problems are discussed and a dynamic steady-state solution within the realms of the classical theory of elasticity is provided. But the complete stress and displacement distributions are difficult to obtain, and no attempt is made to arrive at this.

TL;DR: In this article, a combination of remeshing and nodal relaxation was used to study crack propagation in elastic-plastic materials, and substantial crack growth was achieved with less computer time and higher accuracy than in conventional FE analysis.

TL;DR: In this paper, the Laplace transform with respect to time is used to reformulate the problem of stationary crack in a visco-elastic body under plane strain, subjected to dynamic loading.

TL;DR: In this article, the double cantilever beam specimen for fracture testing was investigated for large displacement conditions, and explicit relations for use in experimental situations were derived for two different loadings, transverse force and bending moment.

TL;DR: Safety factors (uncertainty factors) are used to avoid failure in a wide variety of practices and disciplines, in particular engineering design and toxicology.
