Q
What are the possible effects of rolling with insufficient camber?
A
Thicker centre (long edge) Thicker edges than the centre (Lateral spread)
2
Q
If insufficient camber has been used in rolling and the sheet exhibits long edges, what is the stress pattern
A
residual stress pattern of compression at the edges and tension in the centreline
3
Q

Compression on the centreline and tension on the edges
4
