The effect of ethylene comonomer content on the crystallization, mechanical and viscoelastic properties of VERSIFY copolymers was studied by DSC, DMTA, POM and WAXD.
Wang approximated the foundation as an elastic or viscoelastic medium and proposed a fast prediction method for the response of a circular shallow tunnel foundation under surcharge loading.
Wang 将地基近似为弹性或粘弹性介质,并提出了一种堆积载荷作用下圆形浅隧道地基响应的快速预测方法。
