Rolling sheet plate rolling sheet and plate rolling is similar to forming sheet metal with press brake.
Deflection of sheet metal triangular plate.
The follow web pages contain engineering design calculators that will determine the amount of deflection and stress a flat plate of known thickness will deflect under the specified load and distribution.

The thickness is not more than about onequarterof the least transverse dimension and the maximum deflection.
Is not more than about one half the thickness.
It is seen that the present numerical results lie in the so called bounds of the present.
In the small deflection case three types of elements the hsieh clough tocher triangular plate element the felippa quadrilateral plate element and the dupuis triangular shell element are used to calculate the stiffness of two simple panels a sectional circular cylinder and a paraboloid and a spherical cap.
The plate is flat of uniform thickness and of homogeneous isotropic material.
It can be a black art or maybe magic but in reality it is neither.
It comes down tounderstanding the properties of the material and how pressure from the rolls can affect those properties.
Many of the stress and deflection equations and calculators referenced from.
In general linear plate deflection theory is inadequate to accurately predict the displacement of thin plates.
Flat plates stress deflection equations and calculators.
The plate is nowhere stressed beyond the elastic limit.
The non dimensional maximum central deflection w m of the back face sheet and structural response time t for rectangular sandwich plate β 0 5 are plotted in figs.
6 a and b as a function of the non dimensional impulse i respectively.
Cells on the right will output the desired values.
Especially in cases where the plate deflection exceeds the plate thickness.
Figure 1 depicts the displacement re sponse of a 3 0 x 5 0 aluminum plate with a thickness of 3 32.
You only have to insert interior angle flange lengths k factor inside radius and material thickness.
With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements.
