弹性、热弹性物性值反问题的边界元分析
Boundary Element Analysis of Inverse Problems of Elastic or Thermoelastic Material Parameters
【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。
【Abstract】 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.
