material: ST-S-CR340LA-HD50G50G-U
Thk: 1.2mm

Layout phase: drawing crack at the cornor

main reason to crack: insufficient material flow,origin part thinning is 22.5% , min. area is only 0.93mm per AF simulation
per GD&T call out,cornor area is not critical area
propose to change cornor area feature to reduce material friction and improve flowing
optimized feature thinning is 10.8% (min. area is 1.07mm) per AF simulation
per CAE, change part model and print
per CAE, change part model and print,part thickness came out 1.05mm
surface spring back: adjusted after optimizing simulation
1st tryout part surface deviation
2nd tryout part surface with optimized simulation
