封閉泡沫材料之受壓力學行為

Abstract

本研究計畫主要想探討的課題是封閉泡沫材料的受壓力學行為。封閉泡沫材料由於 微觀結構十分特殊，其力學及其他物理特性亦十分特殊。由於這些獨特的力學及物 理特性，此等材料在諸多工程領域上十分地實用。然而，設計及最佳化利用這類材 料的相關知識，卻仍未臻完善。本計畫的目標是藉由系統化的仔細觀察及實驗量 測，再輔以解析推導及數值模擬，將泡沫材料的微結構與整體力學行為間的關聯性 建立起來。並從而了解各幾何參數對整體力學特性之影響，以期作為封閉泡沫材料 於各工程應用領域中之設計參考。

This study is concerned with the mechanical behavior of closed-cell cellular materials. In particular the mechanical properties of closed-cell foams under compressive loading are of interest. The closed-cell foams exhibit extraordinary mechanical and physical characteristics which make them attractive candidates in various engineering applications. The knowledge regarding the design and use of this class of materials, nevertheless, is beyond fully understood. The present study aims to establish the connection between the compressive behavior and the geometric features of the foam microstructure, by means of experimental and numerical/analytical endeavors.
