基本解釋

For geometrical nonlinearity, Updated Lagrangian formulations are adopted to derive the tangent stiffness matrix.
列式法求解切線剛度矩陣來考慮幾何非線性。
Numerical calculation process to obtain the tangent stiffness matrix of structure is deduced and geometric stability of different types of structures are analyzed.
推導(dǎo)了鉸接桿系結(jié)構(gòu)切線剛度矩陣較為簡(jiǎn)便的計(jì)算生成過程，便于在編程中實(shí)現(xiàn)。
As a result, the element tangent stiffness matrix is symmetric and is updated by using the total values of the nodal variables in an incremental solution procedure.
因而，得到的單元切線剛度矩陣是對(duì)稱的，此外在增量求解過程中用節(jié)點(diǎn)變量的全量進(jìn)行更新。
