增量塑性理论 meaning in English

incremental plastic theory

In the finite element method analysis , the constitutional relationships of steel and three - dimension compressed concrete were conducted by using increment plastic theory . in the paper a serious of joint models were analyzed by using the program ansys and the mathematical formulas for determination of load - carrying capacity of shearing and bending in the joint region were also given . at last the influence of many parameters to the load - carrying capacity in the joint region was analyzed and some suggestions were given for the design in the practical projects
在有限元分析中，用增量塑性理论推导出钢材以及三维受压混凝土的本构关系，重点是三维受压混凝土的本构关系，建立了模型的单元刚度矩阵，给出了程序中非线性方程的求解方法，并用ansys软件计算了一系列节点模型，得出了节点域的抗剪、抗弯承载力及各参数对节点域承载力的影响情况，并用试验结果和计算公式验证了有限元计算结果。
