摘要

PROBLEM TO BE SOLVED: To accurately analyze a creep deformation of a resin member, for simply and easily measuring the quantity of the creep deformation of a test piece formed from a resin, and simply and easily determining the deformation mode of the member.;SOLUTION: In step 4, a reference vector ν1 and a displacement vector ν2 are calculated by a stress analysis. In step 5, a bend mode, a tension mode or a bend/tension mode is set as a deformation mode of a node 6, with a calculated angle α as the angle formed by the reference vector ν1 and the displacement vector ν2. In step 6, creep coefficients C1-C4 of the node 6 are set from the deformation mode. In step 7, a member model 5 which has the creep coefficients C1-C4 set in units of the node 6 and is processed is the object of processing, and creep distortion εcr is analyzed.;COPYRIGHT: (C)2005,JPO&NCIPI
