Thanks for the reply FEA way. Just for context, this is a wheelchair hitting a wall and not a car crashing into a wall. The stresses and deformations are low, hence, why I was thinking of Linear Dynamic (Modal Time History) or even linear static given the 'if the frequency of a load is larger...

Thanks Greg, The peak impact force being Fmax = (m * v^2) / s ? Which is twice the average force = (½ m v^2) / s

I am running the FEA of a wheel hitting a wall and trying to determine whether I have to use a dynamical simulation, or whether a static simulation can give reasonable results instead. I am interested in the stresses and deformation of the wheel parts. Question 1 The Solidworks Simulation help...

I am currently a mechanical design engineer contractor PAYE through an agency (UK). Speaking with a colleague at work where his contract is coming to an end. His plan is to only take on roles through his personal service company and build up a group of clients over time. His plan is to...

Hi FEA way and SWComposites - thanks for the help btw. I'm having a look at Moldflow, Moldex3D and Fibersim. I think the best current method I have available now is to either use a low number of thick plies and extrude into a solid elements within Ansys ACP, or use oriented elements with...

Hi SWComposites, thanks for the reply. Is there another approach you would suggest, instead? Perhaps in another piece of software? Or is it a problem without a current solution which can only be solved with testing & validation? Additionally, if the failure theories in Anaya are not...

So I am looking at the method in general, but I will try to give you an idea of the type of parts if could be used for - these are just generic examples. https://st.mascus.com/imagetilewm/product/hso/volvo-link-arm-volvo-l180e,99295602_1.jpg The fibre could be UD down the length of the arm and...

Not sure I understand because as the fibre direction changes over the part the isotropic properties stiffest direction changes too. So unless you were modelling a part with no fibre direction change you would need the mesh element directions to change over the part volume.

Please could you go into further detail about the macroscale approach you mentioned? My current approach to this method is to model and mesh in normal 3D, then orient each element to have the macro-orthotropic properties in the correct direction for the fibre direction at that point in the...

Thanks for the reply FEA way. Hmm, I think method is good if you have say up to 20 fibres through a volume, but in this case it is thousands plus tows. Additionally, though I may know the general placement and path of a group of fibres, each fibre may deviate. I have test data for the composite...

Hi there, The composite I am looking to simulate has long fibre cast into a matrix (metal-matrix-composite), and is not layered up like an epoxy-carbon. The fibres are sometime uni-directional and sometime follow a 3D path. The 'traditional' approach for composite FEA is to model the plies on...

Hey, I am trying to finalise a machining drawing of a part shown in it's finish state here: https://postimg.cc/DWDPQcYm. The part is made via an unusual casting process - the part is cast between two plates, which once removed only leaves the middle profile surface (labelled A) and end surface...
