简介:首批“中国模具对标德国模具基准化分析项目”在宁波、黄岩落地实施,经过前期紧锣密鼓的准备,项目进入了模具企业现场调研阶段。2018年4月22日下午,来自德国弗劳恩霍夫应用研究亚琛模具研究院(WBAAachenerWerkzeugbauAka-demie)的3位德国专家ThiloKonradSchultes先生、MoritzWollbrink先生和TimGraberg先生到达中国,中国模具工业协会秘书长委派中国模协田慧卿博士全程陪同协助,3位德国专家在田博士的安排下,对中国模具工业协会遴选的浙江宁波、黄岩的10家模具企业开展了为期一周的、深入的现场调研工作。
简介:本文通过二维准连续介质法模拟三角型压头在纳米压痕试验中测量铝薄膜材料断裂韧度的过程,得到了相应的载荷-位移曲线,计算出了铝薄膜在纳米尺度下的断裂韧度(KIC)和相关的力学性能参数。数值结果显示:单晶铝薄膜材料在纳米尺度下的断裂韧度(KIC)为0.216MPa·m^1/2,预测值与相关试验结果较吻合,从而表明使用准连续介质法预测纳米尺度下薄膜材料的断裂韧度是可行的。在研究中发现:对应于载荷-位移曲线的急剧下降区域,相应的位移云纹图中有明显的压痕变形集中现象,表明此处是径向裂纹发生的准确位置。计算结果证明,这种载荷-位移曲线和位移云纹图相结合的方法是计算薄膜材料径向裂纹的有效方法。
