Since liquid crystals are not light-emitting materials, LCDs need to equip with back light units (BLUs) to provide light as light sources.
One key component of the BLU is light guide plate (LGP).

Where d is internal diameter, t is wall thickness.
S—N curve equation in BS7608 and DNV C203 is : （7） Among which m, C is material constant, N is stress cycles, Ds is stress range.
Stress concentration and welding residual stress is the key factor affecting the welded joint fatigue property.
