- Modelo resorte-paríicula para telas hiperlasticas MARIO GÓMEZ MANUEL GARCÍA OSCAR RUIZ PIERRE BOULANGER Ingeniería Spring− particle model Nonlinear behavior Hyperelastic material This article presents a computational model to simulate the deformation of hyperelastic fabrics. Themodel is based on a spring−particle approach and it simulates the interaction of a textile tissue with a forming body.The fabric is represented by rectangular meshes of springs. This fact enables the model to behave orthotropically andtherefore it is possible to simulate the warp and weft properties. The constitutive relations preserve the naturalhyperelastic capabilities of the cloth. In the model developed herein, initially the cloth lies in its relaxedun−deformed state. Then it is given an initial deformation that guarantees no contact nor intersection with theforming rigid body. Finally, the deformed cloth is realised, and moves iteratively towards an equilibrium location.The final equilibrium location is reached when the internal forces are balanced by the external contact forces causedby the rigid object. This is achieved when the stop criterion has been satisfied. 2007 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49615115 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.151 Vol.74
