Abstract

Bu çalışmada, eğilme ve eksenel deformasyon rijitliğini içeren Lagrange Sonlu Elemanlar formülasyonu, kumaş ağırlığını içerecek şekilde genişletilmiş ve kumaşların büyük eğilme ve burkulma deformasyonlarının hesaplanması için incelenmiştir. Deformasyon sonuçları, literatürdeki sonuçlarla karşılaştırılmıştır. Hesaplanan sonuçların, daha önce yayınlanan sonuçlarla oldukça iyi uyum içinde olduğu gösterilmiştir

Keywords

PREDICTION OF LARGE DEFORMATION BEHAVIOR OF FABRICS USING LAGRANGIAN FINITE ELEMENT FORMULATION

Abstract

In this study, the Lagrangian Finite Element formulation, covering both the tensile and bending rigidities, is extended to include fabric weights and then exploited for the prediction of the large bending and buckling deformations of fabrics. The deformations results are compared with those published in the literature. It is shown that there is an excellent agreement between the calculated results and the previously published results

Keywords
