Weld Study
• Introduction/Background
– Use two plates, a flange (or bottom) plate and a faying pad,
to make up a flange.
– The simplest faying pad configuration is to instill the use of
a large transverse fillet weld across the end of a faying pad.
– This will permit the use of thinner plates with lower section
moduli and take advantage of its higher allowable stresses.
Weld Study
• Problem Description
– Objective of the project
– Finding the average
stress in the weld
– Effects
Weld Study
Weld Study
• Methodology/Approach
– An finite element analysis will need to be conducted in
order to accurately predict the average stress in the weld.
– This analysis will include a model of a transversely loaded,
100% efficient, double fillet-welded, T-joint.
– The analysis will be performed using the Abaqus Finite
Element program.
– 60 models will be developed to establish the framework for
this analysis.
Weld Study
• Expected Outcomes
– The hope of this project is to show that the load in the
faying pad will contribute a greater percentage of the total
load going into the plate than the weld will.
– By finding the stresses in the infinite plate and in the faying
pad, one will be able to calculate the stresses along the
throat of the weld.
