To eliminate the unwanted axial strain constraint, in Abaqus the stretch dL/dS at the node of each such element is taken as an internal variable, local to the element (a third internal node is created for this purpose, and so it is not shared with neighboring elements.) 

Above paragraph is excerpted from chapter about Euler beam theory in ABAQUS theory manual.

This is a free tool to simulate the fragment of brittle materials. You can use it to calculate the fragmentation of some differernt materials with different weakened styles. Also you can use different model to analyze your fragment process. The tool and its introduction are showing the attachment.

hi,

  i am new to abaqus , i working on a simulation of wire drawing process in Abqus explict, i had modeled the die as a Axisymmetric rigid body and the surface as a analytical rigid surface and the wire as a axisymmetric deformable body and i had given the materail properties of wire and define the contact properties between the die surface and the wire surface, when i started the simuation, there is excessive deformation of the elements in the wire, as the elements pass through the die they are trying to regain back. some please help me how to get rid of this issue.

The Virtual Conference on Nanoscale Science and Technology (VCNST) is in fact so much more than just another conference. We have an opportunity together to be explorers as we enter a new era of sharing and dialoguing about science.

Dear all,

 At our website we maintain a list of upcoming conferences on contact mechanics and related fields, e.g. solid mechanics, tribology, railway vehicle dynamics, etc.

Which conferences and other events do you attend? Send me a note and I'll add them to the list.

Best wishes,

Edwin Vollebregt
