粘弹性体半平面问题位移场的研究

The study about the displacement field of viscoeleastic body

利用散斑照相的方法对半平面粘弹性体位移场进行了研究．利用半透明材料采用透射成象的方法作记录，分别给出了逐点分析结果和全场的等位移条纹图．并由粘弹性理论中的对应原理给出了粘弹性模型位移场的理论解．在此基础上进行了实验与理论结果的比较．

The speckle photo method is used to study viscoelastic model displacement field. The point by point analysis results and whole displacement field graph of translucent material are obtained by using transmission model method, and the theory results of viscoeleastic model displacement field are given according to the correspondence principle in viscoelastic theory. Based on this, we compare experiment results with theory results.
