弹性阶段弯曲下尺度效应的研究

Study of the size effects on the micro-scale has a very high level in the plastic, but the size effect in the stage of elastic deformation stage of the existence is not a very good argument, On the non-homogeneous finite elastic deformation theory,the paper discusses the size effect of bending in the elastic stage and deducing out the bending format of the new elastic theory.Combined with the strian gradient theory,we analyzed the size effect of three dot bending in the elastic stage. From the results of the analysis, When the object size is characteristics of considerable size, there is a strong measure of the size effect in the phase of the elastic stage , but to be slightly smaller the scale effect in the plastic.
