Abstract

Abstract We exploit the possibility of deforming a shell by assigning a target metric, which, for 2D structures, is decomposed into the first and second target fundamental-forms. As well known, an elastic shell may change its shape under two different kinds of actions: one are the loadings, the other one are the distortions, also known as the pre-strains. Actually, the target fundamental forms prescribe a sought shape for the solid, and the metric effectively realized is the one that minimizes the distance, measured through an elastic energy, between the target and the actual fundamental forms. The proposed method is very effective in deforming shells.

目标度量和壳体成形

摘要我们通过指定目标度量来利用使壳变形的可能性，对于2D结构，目标度量被分解为第一和第二目标基本形式。众所周知，弹性壳在两种不同的作用下可能会改变其形状：一种是载荷，另一种是变形，也称为预应变。事实上，目标基本形状为固体规定了一个所寻求的形状，而有效实现的度量是通过弹性能量测量的目标和实际基本形状之间的距离最小化的度量。所提出的方法在壳体变形方面非常有效。

期刊介绍： The aim of Curved and Layered Structures is to become a premier source of knowledge and a worldwide-recognized platform of research and knowledge exchange for scientists of different disciplinary origins and backgrounds (e.g., civil, mechanical, marine, aerospace engineers and architects). The journal publishes research papers from a broad range of topics and approaches including structural mechanics, computational mechanics, engineering structures, architectural design, wind engineering, aerospace engineering, naval engineering, structural stability, structural dynamics, structural stability/reliability, experimental modeling and smart structures. Therefore, the Journal accepts both theoretical and applied contributions in all subfields of structural mechanics as long as they contribute in a broad sense to the core theme.
