Examples' manual for *USER_LOADING option

Melissa Adoum, Vincent Lapoujade CRIL Technology Correspondence The aim of this study is to understand how the *USER_LOADING option works and to give some examples of its use. This option uses the subroutine loadud, its usage will be described step by step and it is illustrated with four examples : • Plate loaded with time dependant pressure, • Plate loaded with displacement dependant pressure, • Randers-Pehrson & Bannister Tests, • Plate loaded by an explosion of 5kg of TNT. Some of those examples use loadings that can be also applied through LS-DYNA existing options, thus the results obtained with the user loading option could be compared and validated.
