When foam density increases from 0.11 to 0.22 g/ cm~ 3, the plastic collapse strength rises from 0.20 to 1.29 MPa, while the elastic modulus of the closed cell aluminum foam increases from 0.70 to 1.17 GPa. 当泡沫铝密度从0.11增加到0.22g/cm~3时,其屈服强度从0.20增加到1.29MPa;弹性模量从0.70增加到1.17GPa。
In some degree, the foam economy led by the rupture of stock market foam played an important role in the process, and the collapse of foam economy produced a very bad influence to Japan economy. 究其原因,与股市泡沫破裂所引发的泡沫经济有很大关系,泡沫经济的崩溃对经济的影响是惨重的。
The results show that the stress strain curve of ceramic foam under compression is not similar to that of the foamed material characterized by three distinct regions, and it only consists of a collapse plateau region and a densification region but without an elastic region. 结果表明:泡沫陶瓷受压缩的应力-应变曲线并不具备泡沫材料受压缩的典型应力-应变曲线的三阶段特征,它没有明显的弹性变形段,只有屈服平台段和紧实段;
Results show that the compressive process of closed-cell aluminum foam material was characterized by three deformation stages: linear elastic stage; plastic collapse stage; 结果表明:闭孔泡沫铝材料的压缩过程具有明显的三阶段变形特征:线弹性阶段,塑变崩溃阶段(初始坍塌和延续坍塌),致密化阶段;
