Fatigue Design of Tanker Semi-trailers

Abstract

• The aim of this paper is to 
establish a methodology for the 
fatigue analysis of a cryogenic 
tanker semi-trailer vehicle to 
allow to design with this against 
this failure. Failure will be 
analyzed in the base material 
of the weld and heat affected 
zones (HAZ) facing the most 
critical manoeuvres to which 
the vehicle may be subjected. 
So, critical manoeuvres must 
be established in the fatigue 
calculation, the material model, 
etc.
There will be also a numericalexperimental correlation of 
fatigue welded test pieces 
allowing the validation of the 
numerical weld model.
