大神看看这个钢板的初始缺陷怎么加

新手 被导师赶鸭子上架初学ABAQUS
问题是这样：我要模拟一块钢板（见下图）在受到轴力，剪力和弯矩时候的变形情况 这个钢板是用壳体建立的
中间的正方形是钢板，两边的阴影是过渡单元

然后要引入初始缺陷
文章里的要求是这样的

6.2.4 Initial Geometric Imperfection初始几何缺陷

Both initial local andoverall geometric imperfections were incorporated in the model. Superpositionof local buckling mode and overall buckling mode with the measured magnitudeswas carried out. These buckling modes were obtained by eigenvalueanalysis. In the present study, the initial imperfection of the steelplate, which was presented in the form of initial out-of-plane deflections, wasdetermined from the lowest buckling mode (Eigen mode 1). All buckling modespredicted by ABAQUS eigenvalue analysis were generalized to 1.0 and thebuckling modes were factored by the measured magnitudes of the initial localand overall geometric imperfections. The maximum magnitude of the initialgeometric imperfections at the plate was taken as 0.003 hp (hp=the height of the steel plate), which was suggested by Wright (1993).

我的问题是这样：我的模型里的初始缺陷是怎么样的？我搜索了论坛的帖子，发现有人的初始缺陷是一个公式。而我的初始缺陷难道仅仅只是一个值么？（ 0.003 hp）

第二，初始缺陷如何添加的问题

搞定了吗
