The loss of material strength due to higher sheet thicknesses are considered in different ways, which depends on the assessment standard used.

In this chapter the methods of considering the loss of strength in sheets with higher thicknesses is explained in detail for every standard implemented in WeldFEM.


Reduced Material Strength DVS 1608 And DVS 1612

According to the DVS 1612 material strength values shall be reduced for sheets with thicknesses greater than 10 mm.

This done with with following formula: ;



Reduced Material StrengthDIN EN 13001-3-1

According to the DIN EN 13001-3-1 no material strength reduction due to higher sheet thicknesses is intended.



Reduced Material Strength Eurocode 3

According to Eurocode 3 material strength values shall be reduced for sheets with thicknesses greater than 25 mm.

This done with with following formula: ;
