Parametric Modelling of Mechanical Performance of Nonwovens for Design and Manufacturing

该项目的主要目的是开发一个参数化的数值模型，以模拟非织造布的时间依赖性，各向异性，弹塑性和损伤材料性能的基础上，他们的制造参数（粘合面积/图案，基重，ODF等）。和纤维性能。该研究项目是与美国NC州立大学非织造布研究所合作进行的，旨在分析非织造布的力学和微观力学。一些具体目标如下：整合连续和不连续的建模方法，为非织造布设计者和制造商开发一个多尺度，实用，参数化的数值建模工具，开发一个多尺度的损伤标准，用于评估非织造布的故障，验证开发的数值方案与实验案例研究，开发一个独立的软件与GUI和纤维性能数据库的工业合作伙伴，使他们可以实施开发的建模方案，设计所需的强度，柔软度和机械性能的非织造布。

The main aim of the project is to develop a parametric numerical model to simulate time-dependent, anisotropic, elastic-plastic and damage material properties of nonwovens based on their manufacturing parameters (bond area/pattern, basis weight, ODF, etc.) and fibre properties. The research project is carried out in collaboration with The Nonwovens Institute of NC State University, USA and aims at analysis of mechanics and micromechanics of nonwovens. Some of specific targets are as follows:Integrate continuous and discontinuous modelling approaches to develop a multi-scale, practical, parametric numerical modelling tool for nonwoven designers and manufacturers,Develop a multi-scale damage criterion for the assessment of failure of nonwovens,Verify the developed numerical scheme with experimental case studies, Develop a stand-alone software with a GUI and a fibre-property database for industrial partners so that they can implement the developed modelling scheme for designing nonwovens for required strength, softness and mechanical performance.
