项目摘要

The aim of the present research is to propose a new approach for the identification of the mechanical properties of individual component layers of metal or metal/polymer composite sheets by elasto-plastic inverse analyses. The present findings are summarizing as follows :(1) For a bimetallic sheet, a set of material parameters in a constitutive model of cyclic plasticity for individual layer was successfully identified by minimizing the difference between the experimental data (the tensile load vs strain curve in uniaxial tension and the bending moment vs curvature diagram in cyclic bending) and the corresponding results of numerical simulation. The method was verified by comparing the simulated results using the constitutive model incorporating the identified material parameters (eight parameters for each layer, i.e., totally sixteen parameters in an isotropic/kinematic haredening model) with the experimental results on a stainless steel/aluminirn composite sheet.(2) This method was also applied to determine the material parameters for a polymer in a polymer-layer sandwiched aluminium sheeL For that purpose, the experimental data of the transverse shear deformation of the polymer-layer appearing in V-bending experiments was used.Furtheremore, it is worth noting that :- this method has an advantage of using the experimental data for a whole composite sheet but not for individual component layers (the identificationis is possible without performing a time-consuming process of the removal of a layer from the composite sheet).- the identification procedure is based not on the conventional try-and-error approach but on an advanced optimization technique.
本研究的目的是提出一种新的方法,用于识别金属或金属/聚合物复合材料板的弹塑性逆分析的各个组成部分层的机械性能。(1)通过将单轴拉伸时的拉伸载荷-应变曲线和循环弯曲时的弯矩-曲率曲线的实验数据与相应的数值模拟结果之间的差异最小化,成功地确定了单层板循环塑性本构模型中的材料参数。该方法通过比较使用本构模型的模拟结果进行了验证,该本构模型包含识别的材料参数(每层八个参数,即,共16个参数的各向同性/运动学硬化模型)与不锈钢/铝复合板的实验结果。(2)该方法还用于确定聚合物夹层铝板中聚合物的材料参数。为此,使用了V形弯曲实验中出现的聚合物层横向剪切变形的实验数据。- 这种方法的优点是使用整个复合材料板的实验数据,而不是单个组件层的实验数据。(识别是可能的,而不需要执行从复合片材去除层的耗时过程)。识别过程不是基于传统的试错法,而是基于先进的优化技术。
