ottosen meaning in English

奥托森

For the structural engineering , the constitutive relations of concrete members under the strength will be nonlinear or elasticoplasticness , in this paper , ottosen constitutive model is adopted , and mohr - coulomb strength principle is selected as destructive principle , the concrete cantilever beam is analyzed by using nonlinear efgm , the calculation result by nonlinear efgm is compared with the analysis software of adina , the comparing proves that efgm used to dissolve the concrete nonlinear problem is feasible
目前，无网格伽辽金法主要研究都集中在线弹性材料上，在结构工程中，混凝土构件受力后的本构关系为非线性或弹塑性，本文首次在无网格伽辽金法中引入混凝土的ottosen本构模型和莫尔库仑强度破坏准则，对混凝土悬臂梁等构件进行了非线性无网格分析，并与国际著名结构分析软件adina的计算结果进行了对比，表明采用无网格伽辽金法解决混凝土非线性问题是可行的。
