Hello.
I would like to ask if there is a specific formula for calculating the internal stress of thick wall pipe subjected to shear in a plane perpendicular to the axis of the pipe.

Hello Terry.
Thank you for your answer.In your analysis are you considering the weld as a material with different properties? Are there any consideration to take in account except the weld geometry?
This weekend I shall finish the geometry of my model regarding with the R1MS method and I shall...
Hello.
I would like to ask help in trying to evaluate a structure which is welded.I am no expert in Abaqus but I like to get to the bottom of it and with the help of Eng-Tips colleagues.
I had attached the drawings in a simplified form for my problem.Essentially I have the same principle for the...

Guys what I am doing wrong in my calculations?
The summation of moments of Fx component and the Fy component of the hydraulic cylinders around pint A (clockwise) is lower than the moment of By at A (counterclockwise).
Is there a problem that I tried to solve the linkage putting the conditions...
Hello.
I found out where is the center pf gravity. It is 1815 mm away to the right from A.The total mass of the truck is 33 tons = 323619 N. The force developed by hydraulic cylinders is 490625 N.
From the first look I don't think the cylinders can lift the load.
Please advise.
Thank You.
P.S...
Hello Indeed:
I just wanted to do the calculation for one side.
Meaning: 1 cylinder = 245 kN, for the left side I have 22 tons - calculating for 1 cylinder will be 22/2=11 tons.I made some rough assumptions because I don't have all the data so I choose Rby=120kN.If Rby=22 tons than take in...
@jlnsol...the truck with cargo has maximum 34 tons.Truck (10 tons) + cargo (16 tons) + some auxiliaries (8 tons) = total weight 34 tons.
They had calculated that with regard to all CG (truck,cargo,auxiliaries) when the truck is lifted on the 2 bogies the weight distribution is : front bogie 22...
Hello.
Unfortunately the person with CG data is on a vacation, and I can get the data only Monday.
Hope that you will have the patience.
I wish you a good weekend.
Thank You.
what's the link geometry with the truck lifted ?
I don't understand the question...
The hydraulic system is a pressure sensing load - the variable displacement pump shall deliver the flow in accordingly with load.
rb1957...both hydraulic cylinders are synchronized by a mechanical linkage.
The back of the truck is lifted by another 2 hydraulic cylinders.
The CG i can deliver only tomorrow, because the person who has the data gave me only the load repartition for the front bogie (22 tons) and rear bogie (12...
