Modelling steel-wood-steel connection. Job aborted. Request for suggestion to changes in model.

(OP)
I created models. Wood: 1200*200*200 steel:600*200*10 bolts: 300 long with diameter 20. I set anisotropic properties for wood and include modulus of elasticity, poisson ration and shear modulus. i want to study the changes in displacement when steel plate is pulled out by force.
I set steps,interaction properties, load, bc condition and finally mesh. Job is ran , however , it is aborted. What solutions shall i take? It is desperating.
My loading is pressure tat act outwards, and equals to 50N/mm2.Bc is encastre at end of the wood.

RE: Modelling steel-wood-steel connection. Job aborted. Request for suggestion to changes in model.

To make the job complete try the following changes (they should work, I checked it on your model and now it runs to completition):
- refine the mesh because it’s rather coarse in your model and there are some bad quality elements
- reduce initial increment size to 0.01, decrease minimum increment size to 1E-15 and change maximum number of increments to 10000
- enable automatic stabilization (specify dissipated energy fraction option with default settings)
- verify correctness of contact pair definitions, if you are not sure how to define them properly then use Find Contact Pairs tool to automatically create contact pairs (or use general contact)

Thank you. FEA way. I solved after refine mesh by partition parts.

Hi guys. In my model, both of the steel plate are pulled by force and i want to record overall displacement of the part" wood". i set a reference point above "wood" but it has strange result. Do u have any idea how to get total displacement from correct location?

To find the displacement of wooden column you can either remove remaining instances from viewport/replace the view with wooden part instance (using display group options) or request history output at selected nodes/reference points (RPs have to be coupled to the mesh first).

By the way, the mesh is still too coarse. Especially around the connections.

White Paper - PLM and ERP: Their Respective Roles in Modern Manufacturing
Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each person’s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
