Purpose: This paper is to numerically predict thermo-elastic-plastic deformation during thermal process. Decreasing material strength in thermal processes causes severer deformation at elevated temperature even under self-weight of huge and heavy products. Design/methodology/approach: A hybrid method is proposed and applied, in this study, to analyse thermomechanically coupled problems such as heat...
In this paper, we discuss some critical aspects of standard numerical models for tsunami simulation. We evaluate the importance of dispersion in open sea and demonstrate that the Boussinesq equations offer a surprisingly good balance between accuracy and mathematical simplicity for tsunami problems. Numerical artifacts of wave propagation in discrete media, with emphasis on effects of staircase boundaries...
The paper concerns shape functions formulations in the scope of the recent methods generalizing finite elements and whose common feature is the absence of a mesh. These methods may also be interpreted as a genarelization of the finite difference approach for irregular grids. The shape functions obtained by the Moving Least Squares an by the GFDM (Generalized Finite Difference Method) approach exhibit...
