## Pressure vessel deflection

Hi,

I have observed in many cases that horizontal pressure vessel with saddle support due to the internal pressure gets circumferentially compressed (vertical deflection).

Can anyone expalin why it behaves so.

## how element quality will affect the accuracy of results

hi all,

I want to know how the element quality is decided.

For example: for warpage of elment if allowable limit is max 15deg, what will happen if it exceeds 30 deg.

On what basis this limit is calculated.

Like this for the other quality parameters also.

plz help

## G value for design

Hi all,

I want to know how the G(Gravity) value will taken as 4g or 3g for the design of the structures.

On what basis the value will be selected.

Any calculation or theory about it, plz tell me.

## Gear Box analysis

hi all,

I am doing the FEA on gear box of wind turbine, which is a very complex system.

I want to carry out  static and dynamic analysis. I want to consider all the gears in this analysis.

If anyone is having experience in the gearbox analysis, please help me. how to simplify this complex system.

If anyone is having any reference documents please forward to me.

thanks

## buckling analysis

hi all,

I am doing buckling analysis of pressure vessel. I want to check the buckling load for individual components.

This pressure vessel is subject to hydrostatic pressure.

So if i want to check this, how to do that. I am not perticular about the softwares.

thanks

Hi,

I am trying to carryout the  analysis of a pressure vessel.
Which is subjected to 100cycles during its life time.
The component is subjected to cyclic loading i.e presure of 0-10 MPa and temperature of -10 to 50 deg.

How to give this cyclic loading to carryout analysis.

Thanks and regards

## fatigue analysis

hi,

Is it necessary to carryout the linear static analysis first before doing the fatigue analysis.

If the stress exceeds the UTS , still can we caryyout the fatigue analysis.

## deformation due preload

hi,

I am performing bolted joint analysis, I want to know the what is the effect of the preload.

If preload is applied/removed whether there will be any effect on the deformation of the bolt and component.

what is the relation between the bolt preload and deformation.

thanks
