Abstract
The soil behavior depends on various factors such as stress path during loading. Most soil behavior models are independent of stress and strain and are therefore unable to predict soil behavior while rotating the main stress and strain axes. According to Multi-laminate theory, in pasty elastic behavior due to the necessity of reflecting the development of stress and strain and its directions on plates passing through a point, the information of these changes remains intact and the behavioral changes will occur at least on one of these plates, which will be reflected in the mechanical behavior of a point and its effects will be seen. In this paper, the rotational effects of the main stress and strain axes are predicted based on the Multi-laminate pasty elastic pattern and compared with the experimental results that Provide adapted results.
