PRETENSION ANALYSIS

Jebunderscore

Hi to everyone,

 I have three load steps that must be analyzed in sequence. In particular:

FIRST LOAD STEP: PRETENSION BOLT (Non linear quasi static)

 

SECOND LOAD STEP: RADIAL LOAD (Non linear quasi static)

 

THIRD LOAD STEP: F = 100 N (Non linear quasi static)

 

I can't to set this analysis. In particular fist and second load steps work correctly.

Third load step don' start from PRETENSION and RADIAL LOAD load steps.

It is like and isolate load step.

 

The settings that i ve performed are shown in attached figures (as example).

 

thank to all (in particualar to @Prakash Pagadala /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' /> )

HI,

 

Third load step will not start from pretension, instead, it will start from 2nd load step. 

 

What are the stresses and displacements at the beginning of the third loadstep?
