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.

该项目的主要目的是开发一个参数化数值模型，根据非织造布的制造参数（粘合面积/图案、基重、ODF等）和纤维特性，模拟非织造布的时间依赖性、各向异性、弹塑性和损伤材料特性。该研究项目是与美国北卡罗来纳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。具体目标如下：整合连续和不连续建模方法，为非织造布设计师和制造商开发多尺度、实用的参数化数值建模工具；开发非织造布失效评估的多尺度损伤准则；通过实验案例研究验证开发的数值方案；为工业合作伙伴开发具有GUI和纤维特性数据库的独立软件，以便他们可以实施开发的建模方案，以设计所需的强度，柔软度和机械性能的非织造布。
