摘要
为了有更好的保护,较强的硬度和较好的柔韧性,所有的生命和植都有皮组织,同样,所有的书也都有封皮.本文将层间摩擦视为扰动,研究具有层间滑动摩擦的精装书状层合板.对于准静态问题,针对三点支撑板弯曲响应和能量耗散进行了详细分析.我们的数值研究表明,就弯曲响应言,精装书的封皮比书芯层更重要;而对于耗能,摩擦导致在每个加载和载周期内产生很大的能量耗散.本研究的核心目标不仅是预测书本状板弯曲变形,而是用这一个代表性的案例,以期望找到有关具有层间滑动摩的多层结构的普遍行为.
For better protection,good toughness and robust flexibility,all life and plants have skin tissue,and likewise,all books have covers.In this paper,interlayer friction is considered as perturbation,and hardcover book-like laminates with internal friction are studied.For quasi-static problems,the bending response and energy dissipation of the three-point support plate are analyzed in detail.Our numerical studies show that the cover of a hardcover book is more important than the core layer in terms of bending response;for energy dissipation,friction results in a large amount of energy dissipation during each loading and unloading cycle.The core goal of this study is not only to predict the bending deformation of book-like plates,but also to use this representative case to find the common behavior of multilayer structures with internal friction.
