| Abstract: | In order to explain the size effect for materials in the scale of micron meters, the strain gradient theory was developed as a new theory during the past 10 years. In the present paper, strain gradient theories and their corresponding applications to material mechanical behaviors are reviewed first. Then, we introduce a strain gradient theory and its main applications, in which no high-order stresses are included. Lastly, the development of strain gradient theoies is forecasted. |
