...-element width leads to a zig-zag crack band when the propagation direction forms an angle with the mesh lines (although the overall propagation path, whose direction is controlled by the maximization of energy release rate, is still approximately correct in large specimens). In contrast...

... release rate for interfacial delamination in a film-substrate structure under hydrostatic pressure and systematically studies the factors influencing the energy release rate in deep-sea soft robots with dimensional analysis. It can be found that a larger elastic mismatch between the film and the substrate...

... / h 2 , β = E 1 2 m 4 + 4 E 1 E 2 m 3 + 6 E 1 E 2 m 2 + 4 E 1 E 2 m + E 2 2 . Replace the bending stiffness in Eq. (2) by Eq. (5) , the energy release rate of the TDCB is subsequently becomes (8) G = P 2 a 2 B...

...Elad Farkash; Leslie Banks-Sills The virtual crack closure technique (VCCT) is a well-established method for determining energy release rates and stress intensity factors in homogeneous, isotropic materials. It has been implemented with four-noded, eight-noded, quarter-point, and other higher order...

... mechanics work, we propose an approximation of the energy release rate field associated with a small surface crack of any boundary location, direction, and orientation combination using the topological derivative. This work builds on the work of Silva et al. (“Energy Release Rate Approximation for Small...

... as the critical interface energy release rate G i c and phase angles ψ and ϕ, are examined using results obtained from Brazilian disk mixed-mode fracture toughness tests. Two material systems are considered. The first contains a delamination along an interface between a unidirectional fabric and a plain woven...

... during microcracking. It is shown that the energy release rate is virtually equal to the area under the softening curve, if the microscopic tensile strength is at least twice as large as the macroscopic tensile strength. This result justifies approaches relying on the concept of constant energy release...

... fields, up to 500 V ∕ mm are applied parallel and anti-parallel to the poling direction, i.e., perpendicular to the crack surface. To determine the different contributions to the total energy release rate, the mechanical and the piezoelectric compliance, as well as the electrical capacitance...
