Stochastic Finite Element Method Based on Laguerre Integrate

摘要：

Aiming at the problems of random responses of stochastic structures, applied Laguerre integrate to the finite element analysis of stochastic structures, and established the algorithm of SFEM based on Laguerre integrate. Examples are solved by choosing different kinds of integrate points and then verified by Monte—Carlo simulation method. The result shows that the new method is of a high efficiency, the first and second moment of response variables reach high precision although the integrate points are few, and the high precision of the third and fourth moment need more integrate points.
