tangent stiffness matrix

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(xiàn)剛度矩陣來(lái)考慮幾何非線(xiàn)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(xiàn)剛度矩陣較為簡(jiǎn)便的計(jì)算生成過(guò)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(xiàn)剛度矩陣是對(duì)稱(chēng)的，此外在增量求解過(guò)程中用節(jié)點(diǎn)變量的全量進(jìn)行更新。
