A Reasonable Method for Constracting General Element DM4 of Thick and Thin Plate with Effectual and Realiable Numerical Solution

摘要: 在研究剪切自锁现象(shear locking)、零能模式(zero energy mode)及分片检验(patch test)等问题的基础上综合考虑了三者之间联系,更清楚地揭示了三者之间内在关系,为建立高效、可靠的厚、薄板通用单元提供了一种合理方法.
- 剪切自锁 /
- 零能模式 /
- 分片检验 /
- 相容约束条件 /
- 合理Kirchhoff约束
Abstract: In this thesis,the interal relations between about shear looking, zero energy mode and patch test are studied, and a reasonable method provided for building general element of thick and thin plate with effectual and realiable numerical solution.
- shear looking /
- zero energy mode /
- path test /
- consistent constraint condition /
- reasonable Kirchhoff constraint
