intrados

1. an arch with a straight horizontal extrados and a slightly arched intrados

一种拱背水平、拱的内面有个轻微弯曲的拱形

2. 2. an arch with a straight horizontal extrados and a slightly arched intrados.

一种拱背水平、拱的内面有个轻微弯曲的拱形。

3. 3.point formed by two intersecting arcs (as from the intrados of a Gothic arch).

两条弧线的交叉点，如哥特式拱门的内尖顶。

4. an arch having cusps in the intrados on either side of the apex

在顶点两侧的内弧面上仍然有尖端的拱

5. an arch having cusps in the intrados on either side of the apex.

在顶点两侧的内弧面上仍然有尖端的拱。

6. The results of FEA method for cold-bending elbow predicted that the point of maximum stress is transferred from intrados to extrados with the increase of the wall thinning.

并应用有限元方法分析了冷弯弯头的应力状况，得出其最大应力发生点随着外拱处壁厚减薄量的增大而向外拱处转移。

7. Collapse load analysis of an elbow with a circumferential through-wall crack in its intrados under in-plane bending

弯管内拱壁含环向贯穿裂纹的极限载荷分析研究

8. intrados radius

拱内弧半径

9. arch intrados

拱腹线

10. intrados springing line

拱腹起拱线 拱内弧起拱线

11. springing of intrados

拱腹起拱线

12. 2. an arch with mutually supporting voussoirs that has a straight horizontal extrados and intrados.

有水平拱背和水平的内弧面的互相支撑的拱石的拱。

13. Crack Treatment of Member and Arch Sheeting on Intrados of Roof Truss-Arched Flume

桁架渡槽杆件和底拱板开裂的处理

14. It is shown that considerable plastic strains accumulated between the intrados and crowns in the middle of the elbow under certain load level.

计算结果表明,在一定载荷作用下,弯管中部两顶线与内缘线之间有较大的塑性应变累积,且塑性应变区域随加载次数增加而增大。
