本节主要讲授与板件局部稳定相关的专业词汇、关键语法、复杂复合句的理解与翻译。

    (1) 板件局部失稳 (Local buckling of plate element)

        ① 板件平衡微分方程(Plate differential equation)

        ② 板件弹性屈曲临界应力(Plate elastic critical buckling stress)

        ③ 板件屈曲系数(Plate buckling factor)

        ④ 板件间约束作用(Constraint actions between plate elements)

    (2)考虑板件局部屈曲设计准则(Design criteria concerning local buckling of plates)

        ① 准则1：不允许发生局部屈曲(Criteria 1: No local buckling allowed)

        ② 准则2：允许发生局部屈曲，使用屈曲后强度

                  (Criteria 2:Local buckling allowed, use post-buckling strength)

【选择题】

1. Local plate buckling influences adversely the load carrying capacity of the section by preventing the attainment of           .

(A) yield strength;  (B) ultimate strength;  (C) ductile failure; (D) brittle failure.

【简答题】

1. How to avoid plate local buckling?

【词汇英译汉】

1. welded box section

2. width-to-thickness ratio

3. elastic critical buckling stress

4. stress redistribution

5. effective width concept

6. post-buckling strength\

7. gross section

【答案】

1. 焊接箱形截面

2. 宽厚比

3. 弹性临界屈曲应力

4. 应力重分布

5. 有效宽度法

6. 屈曲后强度

7. 全截面

【句子汉译英】

1. 在屈曲易发生的位置，有效截面被视为全截面减去孔洞。

2. 板件整体或部分受压易发生屈曲。

【答案】

1. The effective cross section is taken as the gross section minus holes where the buckles may occur.

2. Thin plate element totally or partially compressed is prone to buckle.
