Abstract Introducing a crack in an elastic plate is challenging from the mathematical point of view and relevant within engineering context evaluating strength reliability structures. Accordingly, multitude associated works available to date, emanating both applied mathematics mechanics communities. Although considering same problem, given complex potentials prove be different, revealing variou...

Ionomers are interesting due to their applications in coatings, adhesives, films and packaging materials. A study of the underlying mechanisms for fracture in ionomers is consequently of both practical as well as theoretical interest. In this study, we employ high speed imaging coupled with uniaxial extensional rheometry to delineate the mechanics leading to the brittle fracture of ionomer melt...

The method of fundamental solutions is applied to the computation of stress intensity factors in linear elastic fracture mechanics. The displacements are approximated by linear combinations of the fundamental solutions of the Cauchy–Navier equations of elasticity and the leading terms for the displacement near the crack tip. Two algorithms are developed, one using a single domain and one using ...

In this paper, 2D boundary element stress analysis is carried out to obtain the T-stress for multiple internal edge cracks in thick-walled cylinders for a wide range of cylinder radius ratios and relative crack depth. The T-stress, together with the stress intensity factor K, provides amore reliable two-parameter prediction of fracture in linear elastic fracture mecha...

Abstract In this work, we aim to verify the predictions of numerical simulators, which are used for designing field-scale hydraulic stimulation experiments. Although a strong theoretical understanding process has been gained over past few decades, fracture propagation in low-permeability rocks still remains challenge. Against background, performed controlled laboratory-scale fracturing experime...

The influence of surface porosity on the fatigue life additively manufactured (AMed) EH36 steel samples via selective laser melting (SLM) was studied in-depth by using a numerical method, which pores were simulative AM 3D pores. in both simplified semi-ellipsoid/spheroid and more realistic triangular shapes evaluated first place. Stress concentration factor Kt analyzed ABAQUS assessed FE-SAFE c...

1 The Effect of Cohesive-Law Parameters on Mixed-Mode Fracture R. B. Sills and M. D. Thouless Department of Mechanical Engineering Department of Materials Science & Engineering University of Michigan Ann Arbor, MI 48109-2125, USA Abstract Cohesive-zone models of fracture provide a framework that allows a smooth transition between a strength-based approach to fracture and an energy-based approac...
