[FEM] 四边简支板受压屈曲的有限元与解析解分析 [Finite Element and Analytical Solutions for Buckling of Simply Supported Plates under Compression]

坚持实干、坚持一线、坚持积累、坚持思考，坚持创新。分析用Mdias Gen，正方形四边简支板，受侧向单位线荷载作用，进行屈曲分析。第1阶临界荷载系数：7.449E+002 X方向及Y方向均屈曲为1个半波，也即最容易失稳的模态。第2阶临界荷载系数：1.164E+003 X方向屈曲为2个半波及Y方向均屈曲为1个半波第3阶临界荷载系数：2.072E+003 X方向屈曲为3个半波及Y方向均屈曲为1个半波第4阶临界荷载系数：2.982E+003 X方向屈曲为2个半波及Y方向均屈曲为2个半波第7阶临界荷载系数：4.662E+003 X方向屈曲为1个半波及Y方向均屈曲为2个半波。 PS.第7阶才才轮到X方向屈曲为半个波形。第10阶一阶屈曲临界荷载弹性力学解为744.739与有限元分析结果7.449E+002一致。验算如下： Ncr = Kπ2Et(t/b)2/12(1-v2) = 4 * 3.14159262*2.06*105*10*(10/1000)2/12/(1-0.32)=744.739 微信公众号 ( Wechat Subscription) …

Modeling beam hinge by Release in Abaqus [Abaqus中通过释放转角自由度模拟梁的铰接]

Abaqus / Standard中可以通过弯矩释放模拟梁单元的端部铰接。做个简单笔记。如下图所示，为两端固接，受均布的梁的弯矩图和剪力图。将中间节点一端梁的转动自由度释放后的弯矩和剪力如下图所示。由上图可见，释放转动自由度后，跨中的弯矩为零了。模拟的时候注意，不要同时释放节点连接的所有单元的转动自由度，不然就会出现对角线刚度为零的错误哦。微信公众号 ( Wechat Subscription) 欢迎关注 “结构之旅” 微信公众号
