Hi everyone

I'm a 4th year Mechanical Engineering student completing my individual project on 'Local Plastic Failure Assessment in Pressure Vessel Design by Analysis'.

As part of this I'm trying to run a macro using ANSYS Mechanical APDL to perform the elastic analysis check equation 5.5 (sum of principal stresses less than or equal to 4*design stress) from the ASME code Section 8, Div 2 part 5.3. However, I can't get my macro to run and I'm a bit stuck.

Any help would be appreciated.

Thanks in advance




!Define array



*GET, siga, NODE, i, s, 3

*GET, sigb, NODE, i, s, 2

*GET, sigc, NODE, i, s, 3

! calculate sum of prin stress








!'SIG1: ',sig1(1),'SIG2: ',sig2(1),'SIG3: ',sig3(1),
