| Abstract: | The optimizing design algorithm of symmetric compsite material layer plate with fixed fiber direction and bending load is studied in this paper. The design variable, object funciton and restrain condi-tion is thickness of layer, structral weight and strength or displacement restrain. If strength restrain is adopted, full stress design method is used to optimize the total thickness of element. Then with fixed total strain energy criteria is used to adjust the thickness of each layer so that the distribution of matrial is more reasonable and the weight can be reduced. If the restrain condition is displacement restrian, the criteria method under Kuhn-Tueker condition is used. The examples illustrate that the algorithm in this paper have good efficiency, high divergent speed. |
