hi.
i want to perform a creep analysis. Design temperature of the Vessel is 420C and our client want a creep analysis
T=420
Mat:516 70
Life Expectancy : 175000 hours.
i have studied Section III- NH . based on NH i have to do elastic analysis and compare it to Smt, which is time dependent...
thanks. i understand your way. but two issues aren't clear to me.
1. using this method, the material will get to the plastic region sooner. wont this make errors ?
and is this method acceptable by ASME or mentioned anywhere ?
2. [highlight #FCE94F]ASME PTB-3[/highlight] in its example...
hi
im doing an elastic plastic analysis using ansys. for the material model i used asme sec VIII div2 model.
i have formulated it in excel and double checked it and it's correct.plastic strain at yield point is not zero (gamma_1+gamma_2), why ?[highlight #FCE94F][/highlight] what must i do...
hi.
i am modeling a 2d vessel. all loads and geometry are axisymmetric except one of the loads (like wind)
i want to consider it using harmonic elements in workbench. any idea how ??
workbench uses plane 183 for 2d problems by default and for nonaxisymmetry loads i have to use plane 83...
first my boss then our clients. they believe that el-Pl or div 2,3 is not widely used and are based on lab work and not very industrial.
and many of consultant are not very familiar to the rules of div 2,3 and have fear from these.
also even i m not sure that these rules especially design by...
hi.
im not sure how ratcheting assessment is done Based on ASME code.do we use a special material model like chaboche model for ratcheting? or is just Elastic Analysis and then post process?
please see this : https://caeai.com/blog/brief-discussion-ratcheting
hi to all.
i would appreaciate hearing your thoughts on this.
we want to present and convince that using div 2,3 and EL-PL Method or Fracture is more economic and money saving. do you know any projects in the Fix Equipment field which is designed using Elastic Plastic Method, or using div3...
