碩士 === 國立雲林科技大學 === 機械工程系碩士班 === 92 === The main purpose in this text is an analysis and simulation one dimension shape memory alloy(SMA) nonlinear behavior, making use of and editting of shape memory alloy program and combine with the finite element software, the behavior that under the conditions, such as every kind of loading and temperature.In studying process, the shape memory alloy should the stress, strain, the farmland of martensite spread the of the weight of iron and temperature of relation is an important factor in influence result.Remember the formula of the shape memory alloy, calculate the shape memory alloy load and remove and load the farmland of martensite, with know energy of shape memory alloy.This text the condition that the shape memory alloy often is used for most , doing the finite element analysis, including the shape memory effect( SME) and superelastic , the shape memory alloy temperature and replies the analysis of the power, the shape memory metal alloy combines the analysis of other materials.Also established the method of the program and finite element software ANSYS link, make use of the Fortran program language to edit the program, make the program become the ANSYS sub- program( Subroutine), enlarge the ANSYS function, make the ANSYS be able to analyze the shape memory alloy nonlinear behavior.
