APPLICATION OF THE PRINCIPLE OF MINIMUM POTENTIAL ENERGY WITH MIXED VARIABLES FOR BEAMS WITH LARGE DEFLECTIONS
大挠度弯曲直梁混合变量最小势能原理的应用

Based on the principle of minimum potential energy with mixed variables for beams with large deflections, the paper presents an approximate method for cylindrical bending of large deflections of panels with two edges fixed. Prom the results it is shown that the method is effective and enjoys a high precision.
