چکیده
A discrete constitutive equation for modeling material failure as a decohesion or separation of material to form two free surfaces is a relatively simple approach. However, numerical simulations based on such a model involve considerable complexity including remeshing if the finite element approach is used. Here, a basic formulation involving the simultaneous application of the continuum and decohesion constitutive equations is described together with a numerical approach based on the material point method. Preliminary results indicate that failure propagation can be predicted at an arbitrary angle without the dispersion of the crack front that is often observed with conventional finite elements.

متن کاملTranslation of Psychology Book Titles: A Skopos theory perspective
The focus of current research is the translation of psychology book titles. There are numerous studies in the field of titles translation, but they are restricted in Persian context. The aim of this study is thus to investigate the translation strategies used by Persian translators when transferring English psychology book titles into Persian. To achieve this objective, 245 titles of translated...
