塑性刚度矩阵 meaning in English
plastic stiffness matrix
Examples
- The plastic elemental stiffness matrix was derived by plastic - hinge method
然后用塑性铰法推导了单元的塑性刚度矩阵。 - So , it takes both advantages of spline finite strip method with less node displacement and that of plastic hinge method with convince of getting plastic elemental stiffness matrix
因此该方法兼具二者优点：样条有限条法的位移量少和塑性铰法形成塑性刚度矩阵的便利。 - Moreover , popularizing such system is expected . the following works have been fulfilled within this thesis : first of all , based on the general principle of virtual displacement of nonlinear continuum mechanics , the geometric and material stiffness matrices is presented , several examples show that both of them can give out accurate result
本论文主要完成了以下工作：首先，根据连续介质力学理论构造出的交错桁架结构空间单元的几何刚度矩阵和弹塑性刚度矩阵，算例分析表明这些矩阵能准确地计算出结构的空间二阶效应和空间单元弹塑性杆端力增量，计算结果具有良好的精度。
