Modeling of wear processes by a regularized damage‐plasticity model based on the emulated RVE

چکیده
Wear is defined as damage to the surface of a solid body, involving progressive material removal, due relative motion and frictional contact with another surface. This process usually slow but considered one major factors causing consequently failure component parts during lifetime tools or machines in different applications such tunneling. The implementation conventional local models finite element simulations softening behavior (e.g., plasticity damage) tends toward an ill-posed boundary value problem after onset non-convex non-coercive energy functions suffers from strongly mesh-dependent results. Therefore, regularization strategies are developed overcome mentioned problem, integral gradient enhancement, introducing internal length scale subsequently increasing computation effort. In this study, we present variational approach for model coupled based on emulated representative volume (ERVE). shall be applied numerical investigation wear processes, where fine resolution involved constituents (cut sheet abrasive particles soil) required. We start theoretical derivation model, briefly treatment, prove efficiency new via some examples. Furthermore, results simulation modes single scratch tests presented.

mortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
