Mesh-Insensitive Structural Stress Method for Fatigue Evaluation of Welded Structures

A Battelle Joint Industry Project (JIP) was launched in 2001 to further refine and validate Battelle’s patented mesh-insensitive structural stress method for various industrial applications. As a result of the JIP sponsorship, rapid progress has been made in validating the effectiveness of the structural stress method by effectively correlating large amount of S-N data from drastically different joint types, loading modes, and plate thicknesses.

What Industry is Saying
"Other fatigue software vendors claim to have an effective method, but when you look into the details, they're using a lot of subjective 'fudge factors,' not Pingsha"
Hari Agrawal,
Senior Technical Specialist with Ford Motor Co.
 
"Incredibly significant and compares its impact on engineering to that of mapping the human genome in the scientific world."
Tarsem Jutla,
Caterpillar
 
"It will change the way fatigue analysis is taught at universities and practiced by industry."
Pedro Vargas,
