摘要: 假设弹性势能正比于曲率平方,由变分原理,得到了在外力作用下处于平衡状态的弹性物体的形状方程.通过实验验证了弹性势能的假设.对于特定边界条件,弯曲薄板给出了水滴和心形形状.

关键词: 弹性势能, 弯曲薄板, 心形

Abstract: The shape equation of bending thin plate is derived from variational principle with the assumption that the elastic potential is proportional to the square of curvature. The experimental data confirm the validity of elastic potential assumption. The water drop and heart shape are given for some special boundary conditions.

Key words: elastic potential, bending thin plate, heart shape
