( II ) Rather few works have been done to show the effectiveness of widely employed quasi-static mechanical analysis in the transient LENS process ; as such , both quasi-static and dynamic simulations are performed and compared mechanically to demonstrate the validity of using quasi-static modeling to save computational cost .
