Nonlinear Implicit Analysis in LS-DYNA®

Prerequisites

  • In­tro­duc­tion to LS-DY­NA or equiv­a­lent knowl­edge

Syllabus

LS-DY­NA has ex­ten­sive ca­pa­bil­i­ties for solv­ing im­plic­it prob­lems in ad­di­tion to its more well known ex­plic­it ca­pa­bil­i­ties. This course in­tro­duces you to LS-DY­NA’s im­plic­it fea­tures with a fo­cus on non­lin­ear im­plic­it so­lu­tions for struc­tur­al analy­sis. This course is suit­ed for some­one with pre­vi­ous ex­pe­ri­ence us­ing ex­plic­it LS-DY­NA or with ex­pe­ri­ence us­ing oth­er im­plic­it FE-codes.
