Embossing and restoration technique is conducted as a simple method to strengthen sheet metals. Soft aluminum, mild steel and stainless steel sheets of different thickness are subjected to embossing and restoration at different sheet patterns and emboss height. Deflection tests are then conducted to evaluate the effects of the parameters considered on the increase in the rigidity of sheets. Experimental and numerical methods are both employed in the investigation. Results show that the restoration technique is effective in increasing the rigidity of thin sheet metals. By taking into considerations several important parameters, improvement in rigidity can be enhanced as shown in this study. Also, it should be emphasized that this technique can be used not only for increasing the rigidity of sheet metals but also for making decorative sheets without any special forming tools.
