| 中文摘要: |
| 本文采用边界元法和卡尔曼滤波,对弹性、热弹性问题物性值进行反分析,由有限个观测点的位移值,同时反算出材料的拉压弹性模量Ε、泊桑比ν和线膨胀系数α。 |
| 英文摘要: |
| A method for solving inverse problems of elastic or thermoelastic material parameters is proposed in this paper. It is a combination of the boundary element method and the Kalman filter. Young s modulus E and Poisson s ratio v and coefficient a of linear thermal expansion can be simultaneously concluded by the displacements at observation points. |
