| Research Abstract |
This study investigates a method for reliability analysis of numerical mathematical models of wrinkled membranes. A computer simulation code to analyze wrinkled membrane dynamics is developed. Both the Monte-Carlo method and the data assimilation method are implemented into this code for reliability analysis. A simple problem of square membrane dynamics is provided to verify the effectiveness of both methods. The Monte-Carlo method is applied for sensitivity analysis of model parameters, while the data assimilation method is used for model parameter estimations.
