Unsteady Crack Motion and Branching in a Phase-Field Model of Brittle Fracture
, 2004 Crack propagation is studied numerically using a continuum phase-field approach to mode III brittle fracture. The results shed light on the physics that controls the speed of accelerating cracks and the characteristic branching instability at a fraction ...

Primary crack spacing model of reinforced concrete elements [PDF]
, 2019 The intention of the present study is to develop a unified approach for serviceability analysis reinforced concrete tensile and flexural elements, with a focus on mean crack spacing. The current research is mainly quantitative in nature, with the development of the strain compliance approach based on collected data of 170 tensile and 96 flexural ...

Interactions of double slanted cracks under mode I loading
MATEC Web of Conferences, 2017 This paper presents numerical analysis of double slanted central cracks in square plates under mode I tension stress. ANSYS finite element program is used to model and solve the problem of slanted cracks where the stress intensity factor is determined ...
