Error Estimation And Adaptive Mesh Refinement For Coupled Thermal stress Finite Element Analysisin Casting Systw m
【摘要】 本文以块平衡恢复方法对铸造系统凝固过程中的热应力进行误差估计, 并适应性化分网格. 方法简单, 收敛性较好, 适于任何形式的有限单元
【Abstract】 The recovery technique by equilibrium in patches (REP) is adopted for estimation in thermal stress analysis of casting solidification and adaptive mesh refinement. Though the REP method is simple , higher rate of convergence is achieved and itis adapted for variousfinite elements.
