弹簧片受压过程模拟

1、弹簧片受压过程模拟（几何非线性）问题描述如图一所示，弹簧片尺寸为L=150mm,W=30mm,H=1mm。边界条件如图二所示，A端载荷为F=20N,B端为固定约束。其材料属性如图三所示。图1尺寸信息01FYCnMA。7*Ki屿7zJ日玷皿呻KXorq炉升2L至*zJ自iMTrapir曰BfltKTferwr5fup*.zJdsm&wNJ工正+L1Pa句口NWSCTi5知如Q.J:E跣元率11；3由图3材料属性表卜面将进行分析网格划分将detailsofmesh“中defaultsTrelevence改为100,sizingTrelevencecenter改为fine。如图四所示。-Os
