Derivation and analytical process of calculating shears in triangular element with finite element methods are given 基于上述关系推导了三角形薄板单元的剪力求解过程,然后给出了具体的分析步骤。
Recently professor shi , dongyang etc . have constructed a new 9 parameters triangular element and a new 12 parameters rectangular one by introducing bubble functions and double set parameter method [ 2 ] . it is proved that they are convergent to ( 1 . 0 ) 石东洋教授等通过引进bubble函数和双参数技术构造了新的9参三角形元和12参矩形双参数元,我们分析了其对( 1
Furthermore , we made a great deal of numerical experiments and the numerical results suggest that the new 9 parameters triangular element is more effective than robust element , and the new 12 parameters rectangular element is more effective than the 12 parameters one in [ 5 ] , acm , and the non - complete biquadratic rectangular element 0 )的收敛性,并进行了大量数值实验,结果表明:新的9参三角形元比robust非协调元,新的12参矩形元已有的12参矩形元, acm元,不完全双二次矩形元数值效果都要好
On the basis of experimental research , this thesis applies 2 - dimensional non - linear finite element method to the analysis of transient temperature field on the section by means of relatively high precision triangular element of six joints . when the temperature field is analyzed , finite element reseaus are divided in space field and finite difference reseaus are divided in time field , and then the program is compiled . the computing results are in good agreement with the test data 在试验研究的基础上,本文采用精度较高的三角形六结点单元对构件截面二维非线性瞬态温度场进行了有限元分析,即在空间域内采用有限元网格划分,在时间域内采用有限差分网格划分,据此编制了计算程序,计算结果与试验数据符合较好,程序稳定性好,精度满足要求。
