Detailed Description

Describes small radius bend issues found during sheet metal design analysis.

The small bend radius issue refers to a situation where the bend radius is smaller than the recommended one. When the bend radius is too small, the material is stretched too much, which can cause the material to crack or even break. Additionally, a small bend radius can cause the material to distort, resulting in parts that are not as accurate as they should be.

Contains simple bend that fails the following condition:

\[ \large R_b \geq T \times Rt \]

\[ \begin{aligned} & \small R_b - \text{actual bend radius} \\ & \small T - \text{actual sheet thickness} \\ & \small Rt - \text{expected minimum bend radius to sheet thickness ratio} \end{aligned} \]

Note: This issue can contain only SheetMetal_Bend objects and NOT SheetMetal_HemBend or SheetMetal_CurvedBend. Because small radius bend analysis carried out only for simple bends (SheetMetal_Bend) and simple bends inside compound bends (SheetMetal_CompoundBend.FeatureList()).
