Eigenvalue buckling analysis can only forecast the theoretical buckling strength of an ideal linear elastic structure, because of the unideal property of material and geometrical nonlinearity, most structures can not reach their theoretical strength limit.

特征值屈曲分析只可预测一个理想线弹性结构的理论屈曲强度，材料非理想性与几何非线性使得大多数结构无法达到它们理论强度极值。

The results showed that the tensile strength and elongation at break of the objective silicone rubber increased with the increase of vinyl content in PDM-MVS. The tensile strength was 3.9 MPa and elongation at break was 416%, and the reinforcement effect of PS on silicone rubber was significant when the mass fraction of vinyl was 1.50%. The objective silicone rubber had microphase-separated structure consisting of PS domains uniformly dispersed within a continuous PDM-MVS matrix. The compatibility between the two phases increased with the increase of vinyl content in PDM-MVS.
