关键词：复合材料；随机疲劳；剩余强度；剩余刚度；疲劳寿命

摘要：剩余刚度和剩余强度作为描述复合材料疲劳损伤程度最常见的方法，在应用过程中都存在各自的优缺点。刚度试验成本低，但缺少明确的失效判据使得其实际工程中的应用受到限制，强度虽然存在天然的失效判据，但破坏性试验导致试验成本较高。考虑复合材料结构大多在随机交变载荷下服役，如噪声、振动等。本文通过复合材料常幅疲劳 ...

[中文期刊] 点阵夹芯圆柱壳自由振动分析的波有限元方法核

作者：韩少燕，高汝鑫（西安交通大学城市学院机械工程学院；北京理工大学先进结构技术研究院；大连理工大学工业装备结构分析国家重点实验室）

出处：应用数学和力学 2024 第45卷第1期 P25-33

关键词：点阵夹芯；圆柱壳；自由振动；波有限元；波传播

摘要：针对点阵夹芯圆柱壳的自由振动分析发展了波有限元法．首先基于自由波的传播规律,建立了点阵夹芯圆柱壳胞元的二维波有限元控制方程,相比于全尺寸有限元模型,显著缩减了控制方程的自由度规模;其次,基于Neumann级数推导了约束动刚度矩阵求逆的显式表达式,不仅可以提高计算效率,而且使得固有频率从控制方程中分离 ...
