Here non-linear buckling analysis was intended for static, Riks analysis which will give post buckling behavior also.

In non linear buckling analysis the imperfections are incorporated by scaling of mode shapes from linear buckling analysis. Is it possible to incorporate imperfections from linear buckling analysis and then do a visco step (creep) and finally nonlinear buckling analysis? I think this sequence...

How to do an analysis with imperfection also?. Imperfection is incorporated from buckling modes, so in this case the sequence becomes contradictory.

How to perform a creep buckling analysis in Abaqus? Since Buckling analysis and creep analysis is different steps in Abaqus (Visco & Buckle), how to proceed with high temperature buckling analysis? Thanks in advance.

ok, got it. I had a confusion that whether ss410 will come under low alloy steel, but external pressure chart is specified in Table 1A as you indicated.

What I am looking for is Factor A-Factor B chart for SA-240 grade 410 (plate). Thanks in advance

Whether ASME section II part D gives external pressure chart for SS410 material?

Thank you

In MTC of 304L material it is mentioned that IGC Test as per ASTM A262 practice E is carried out and the material is passed the test. Why L grades are required to be IGC tested (Already this grade is having C<0.03% which means it will not sensitize) ?

It's a good help,Thanks.

ASME section VIII division I allows SS 316 and SS 304 up to 825C. These steels get sensitized at temperatures between 420-850C, so why the standard allows use of these material at these temperatures? At the same time for L grades max. allowed temperatures (316L-475C &304L-650C)are lesser...

Thanks for ur reply. But a 2 mm fillet weld can provide the strength for pressure loading. Then is it necessary to expand the joint? (Crevices are not a concern). I am beginner in this field Just for knowledge, In strength weld how to decide whether groove (surrounding the weld) is to be...

hi, I want to design a tube to tube sheet joint in U tube HX. Tubesheet thickness is 30 mm and tube thickness is 1.245 mm (material SS304L both) and ligament in tubesheet is only 4.5 mm. Since loads are less, a 2 mm strength weld(weld is preferred since leak tightness is important) is...

I am applying preload by displacement Boundary condition. Requirement is to find out the torque required to attain that preload by using contact analysis in Abaqus. Suggest any method to find the torque in Abaqus

I want to model frictional contact in 3D helical thread in Abaqus. I have made 3d geometry of internal and external thread and meshed. Contact with friction is defined between thread surfaces and applied preload. But how to find the torque requirement for that preload? Contact- Small sliding...

I want to avoid this tie constraint at the interface.

Hi I have two regions in my model. One is meshed with C3D8R for contact problem other region is complex and meshed with tet10 elements. At the partition boundary it becomes incompatible. How can I avoid this incompatibility? In one post it is mentioned that connect four C3D8R to two tet10...

I want modulus of elasticity of different steels (ss410, 9cr 1mo, 17-4 PH) at high temperature(550C). Anybody please provide some references. Thanks in advance

I want to evaluate the torque required for producing specified axial tension in the bolt.

I want to model tightening of a bolted joint.After defining the contact, how tightening of nut can be defined. How the torque requirement can be evaluated?
