摘要
本文给出直接求解稳态蠕变应力解的有限元方法 ,针对不同材料特性 ,提出了初应变率法与广义切线刚度法。并写出计算公式与步骤 ,研制了分析程序。有算例说明本方法的优越性。
In this paper,a new way to solve steady creep with finite element method is presented for temperature dependent material properties of symmetric body. According to different material properties,initial strain rate method and general tangential stiffeness method are provided.A computing program is compiled.Some examples are analysed numerically to check its convergency and applicability.
