The Relation Between Interior stress and a governing equation

Abstract

Interior stress is researched by FEM.But FEM with small mesh need long time for the calculation.Therefore it is necessary to research more convenient method. Load displacement curve of the test piece shows internal stress-strain curve. The internal stress-strain equation can be converted into compatibility equation in this report. I compared with the analysis in Fig.6, the total time required for the FEM with a 5 mm mesh was 64 s. The proposed analysis method required 26 s (using a Core i7 PC). This demonstrates that the computational load of the proposed method is low.
