Cohesive Zone Models (CZMs) are well suited for modeling adhesives. In this paper a tri-linear, strain-rate dependent CZM is presented. This model is compared to the bi-linear, strain-rate independent model implemented in ABAQUS TM. The parameters of these models are determined by direct testing of tensile bulk, tapered double …

The cohesive zone model implies that normal stress continues to be transferred across a discontinuity which may or may not be visible as shown in Fig. 6.1. This stress is determined from the softening stress–strain relation that various rocks exhibit in calibrations tests. This transferred normal stress is a function of the separation and ...

Abstract. This paper reviews the cohesive process zone model, a general model which can deal with the nonlinear zone ahead of the crack tip––due to plasticity or microcracking––present in many materials. Furthermore, the cohesive zone model is able to adequately predict the behaviour of uncracked structures, including those with blunt ...

Section snippets Semiempirical heat flux model for biobone ductile microgrinding. At present, the heat flux calculation method commonly used by researchers is [31,32] q = W S = F t v s l c b, where W is the grinding work, and S is the contact area between grinding wheel and the workpiece. F t is the tangential grinding force, v s is the …
