Grid patterns by laser for forming strain analysis
Source abstract
Abstract
This work presents a precise method for creating grid patterns for strain analysis. Laser machining experiments have been carried out on various sheet metal samples. The results show that the proposed method is especially useful for coil coated metal sheets. The laser process does not penetrate nor otherwise weaken the coating when the process parameters are correctly chosen. Thus, the laser applied grid marking has no effect on material formability. Other surfaces studied are hot dip galvanised and plain cold rolled steel. The proposed method fares well when compared to traditional methods such as chemical etching and serigraphy printing.
