The fracture model for softening materials called the Damage Zone Model (DZM), is found to be basically insensitive to small errors in the constituents. However, the constituent Gr (the apparent fracture energy) is deduced from an experimentally determined notched strength by using DZM. This may cau

β¦ Synopsis
The strength of double edged wedge notched tensile specimens of linear elastic linearly softening materials is examined numerically using the Damage Zone Model (DMZ). Failure assessment diagrams are given revealing the dependence of the notched strength on the material strength and ductility, notch size, specimen width and the wedge angle.

A crack in an infinite plate is described as a mixed boundary value problem based on the Damage Zone Model. The boundary value problem is treated by means of Fourier transformation. The resulting integral equations are solved numerically to give stresses and displacements. It is shown that the max
A methodology is presented for the evaluation of the material parameter sensitivity of softening solids. The algorithm is based on the differentiation of the implicit (Euler-backward) return-mapping algorithm used for integration of the constitutive equations and the system of nonlinear algebraic eq
