Detailed Description

Describes irregular size bend relief issues found during sheet metal design analysis.

Irregular bend relief size issue can occur when the bend relief is not proportionally sized to the bend radius and sheet thickness. When the bend relief is too small, it can cause deformation, cracking, or even tearing during the bending process. On the other hand, if the bend relief is too large, it can create weak points in the metal and decrease the overall strength of the design.

Contain bend, one or both reliefs of which fails the following condition:

\[ \large W_r \geq T \times Rt_w \quad \text{and} \quad L_r \geq R_b \times Rt_l \]

\[ \begin{aligned} & \small W_r - \text{actual width of bend relief} \\ & \small L_r - \text{actual length of bend relief} \\ & \small T - \text{actual sheet thickness} \\ & \small R_b - \text{actual bend radius} \\ & \small Rt_w - \text{minimum bend relief width to sheet thickness ratio from expected bend relief parameters} \\ & \small Rt_l - \text{minimum bend relief length to bend radius ratio from expected bend relief parameters} \end{aligned} \]

Note

This issue can contain only SheetMetal_Bend objects and NOT SheetMetal_HemBend or SheetMetal_CurvedBend. Because irregular size bend relief analysis carried out only for simple bends (SheetMetal_Bend) and simple bends inside compound bends (SheetMetal_CompoundBend.FeatureList()).
