Hi, can anyone help me with this apart from DFM, DFA How can we judge the strength of particular sm brackets will be sufficient for a particular application. Please find the attachment I am in the process of designing a bracket for a farm vehicle fender. can anyone suggest what kind of strengthening method (forming rib, embossing, side flange) will suit the application and pass the test standards? please refer to the attachment for the CAD data. Also, refer to the picture representing the specification or requirements.

Note: There are 3 brackets assembled kindly help to find which one has more strength for the given assembled condition.

Thanks In advance
