摘要
This invention may, in that partly changing the stiffness of the structure or to reduce the calculation amount when interpretation and cheomsak a member object, the part rigid fixed part rigid unchanging structure screen, but to calculate effective material as a rigid matrix of the unit structure by the time that the adaptive portion structure-up methods and structures within the unit load on each degree of freedom acts introducing stress distribution coefficient that represents the stress generated in the degree of freedom in each member it was proposed a method for efficiently re-interpret the entire structure. ; This partial rigidity method and recording medium for re-analysis by the finite element structure having a change of the invention is separating the structure with stiffness changing portion and a rigid fixed part and the structure defining the remaining degrees of freedom, including a degree of freedom to the two parts share nine minutes step and stress distribution for calculating a stress distribution coefficient matrix which is defined as the stress which corresponds to my i-th degree of freedom to change members (m) for the j-th degree of freedom in the stiffness matrix and the structure of the rigidity changing part (R ijm) equivalent load vector for calculating the coefficient matrix calculating step, and the condensation step the rigid fixed part through use of an adaptive sub-structure-up methods for condensing a part structure having only remaining degree of freedom, the equivalent load vector for the equilibrium equation condensation only remaining degree of freedom the calculation step and, after configuring the equilibrium equation after the change stiffness and after the change to re-calculate the displacement of the remaining degrees of freedom displacement vector computation step and rigidity displacement vector multiplied by the stiffness change of the modified and stiffness matrices of the change member after changing the rigidity changing member and that includes changing the stiffness change and the change member recalculate the member forces member forces calculated featuring step.
