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.
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) ?
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...
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 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...
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 model tightening of a bolted joint.After defining the contact, how tightening of nut can be defined. How the torque requirement can be evaluated?
I want to select material for a pin operating at 550C. It is simple pin joint with pin under shear load. Please suggest suitable material for this application.
What is the difference between ASTM A387 grade 9 class 1 and class 2. Is it only in tensile properties? Class 2 is having higher tensile strength, does that mean it is having finer grains and less creep strength(Operating temperature 500 C) compared to class 1?
Thanks in advance
I want to select gears for a gear ratio of 10. Can I get this gear ratio by using only one pair of gears. Please suggest best pair of gears.
Thanks in advance
I have to design a U tube STHE. The pressure drop across pass partition plate is 0.5MPa. Can I design it without pass partition gasket. I am planning to provide an o ring at the periphery only. Tube side fluid is water with Temperature rise from 6 to 7 degree Celsius shell side it is air with...
Is there any way to calculate seating load of metallic c-ring or o-ring using theoretical formula or FEM analysis. Compression,material and geometric details of the ring is known.
Thanks
I want to provide metallic seal for a flange connection.This pipe line is used for transfer of fluid at 500 degree Celsius for maximum of 3 hours. Is it possible to reuse the seal for the next transfer. After each transfer flange joint is dismantled.If reusable type of seals are available please...
I am a beginner in mechanical design.I want to select material for a bolt and nut used in a mechanism. Design temperature is 550 degree Celsius and remaining parts are made of SS316L. So I am planning to use ASTM A453 grade 660 and grade 600 for bolt and nut respectively. But galling point of...
