Create Material in Database - 05/26/08 04:59 PM
Hi all,
I am trying to create a new Material in the database : the X6CrNiTi18-10 (austenitic Steel, 1.4541 according to German DIN). My stress analysis is based on B31.3 (CAESAR 5.1 database has this material only according to EN 13480). As far as I know in the column “Allowable stresses” I have to put the value Sh, which is calculated according to B31.3 as the lowest of (Ultimate tensile Stress/ 3) and (yield stress / 1.5).
Which value should I use in the place of yield stress for this specific material: The 0.2% or the 1% proof stress? (In literature I found both values).
Is there any general rule when one should use the one or the other value (e.g. depending on the type of material)?
Thanks in advance
