C ~ 1 natural element method for strain gradient elasticity 应变梯度弹性(GE)理论C~1自然单元法
Based on finite element formulations for the theory in strain gradient elasticity of microstructures, a convergence criterion for the C ~ ( 0-1 ) patch test and its variational basic are first introduced. 基于细观有限元弹性应变梯度理论,首次提出应变梯度有限元的C0-1分片检验条件及其变分基础和一种构造应变梯度单元的方法。
