| 中文摘要: |
| 通过将宏微观应力及应变分成面内及面外两部分,利用理想界面上的面外应力与面内应变连续条件,应用微观应力及应变均匀化方法得到了两层复合材料的弹塑性分析模型,并在此基础上构造了多层复合材料的全量型三维显式本构模型。各向同性层组成的复合材料算例表明了该模型的可靠性,同时该模型完全适用于各向异性层组成的复合材料弹塑性分析。 |
| 英文摘要: |
| A 3D elastoplastic constitutive model of multilayer laminated composites is constructed based on the two layers laminates analysis. In this model, both the macroscopic and microscopic stress and strain are divided into two parts, microscopic stress and strain are uniform in each layer of the laminated composites, perfect interface of the laminated composites is used in two layers laminates analysis. Results of simulation are consistent with that of experiments. The model can be also used in analysis laminated composites with anisotropic elements. |
