Hello everyone.
I am modeling a connection that according to the sections and materials in the numerical model of the article and in the experimental model, bolts fractured. But in the model I made, the bolts increase in length and do not depict fracturing. What adjustments should I make to see the bolts fracturing in Abacus?
I guess bolt property is wrong.
please teach me to correct.
and question else is that diameter of the bolt shank is 21 cm. Do I have to make the hole diameter of the connecting plates 21 cm or 22 cm?
thanks in advance.
This might be caused by visualisation settings of Abaqus and displacements could be exaggerated by Abaqus. Nevertheless, you should check the material properties and you should define plastic region properties (especially plastic strain) properly.
Dear Ali Mirzaee,
Could you explain which failure model has been used in your simulation? As far as I know, if no mechanical failure or damage is imposed on your material properties, you must expect that the deformation will continue forever without any fracture.
Try to describe the descending part of the "Yield Stress - Plastic Strain" curve in Material/Plastic assignments.
dear MohammadHossain Nouripour
any good tutorial movie reference for the failure model in the Abaqus simulation?
to define the mechanical failure or damage for material properties of steel beam?
thanks in advance
