Abstract:
One new
three-parameter stochastic finite element method (TPSFEM) to analysis
probability parametars and distribution of structure dynamical
eigenvalue is proposed. TPSFEM combines finite element method to
structure dynamical eigenvalue with three - parameter method to
reliability analysis. TPSFEM not only solves how to process reliability
analysis in structure problem, but also improves the analysis precision
in reliability. Several examples are given, and the results ascertain
that TPSFEM is feasible and effective.
Key words:

Stochastic Finite element method Reliability
