Good morning.
in the hope of not opening a double post (checking with the search I found nothing useful) I would need your help. I'm a biomedical engineering student and I'm preparing the master thesis. I press that I never had ansys simulation notions and so I'm completely self-taught. I am performing mechanical simulations on a sandwich plane (formed by a central layer of foam, upper and lower skins in carbon fiber and epoxy resin and side elements "in the form of c" always in carbon fiber). This plane has a hole in which a flange is housed and another element in polyethylene and on which a load is distributed (in the simulation I considered a uniform load in the form of pressure). I point out that it is a preliminary analysis, so I do not need a rigorous result (I read that simulations with composite materials are quite complex), so that in the first line I considered the material as having isotropic properties (which obviously in reality is not). what I would need is an opinion on the distribution of loads and tensions, if they can be consistent with the load.
View attachment 44322View attachment 44323View attachment 44324View attachment 44326the thickness of the carbon elements is 2 mm, while the whole plane has a thickness of 29 mm for a length of 1.8 m. as contacts between the elements I used "bounded" for the elements in carbon and "rough" for the elements in polyethylene, since they are only supported inside the hole. the load acting on that plane is 240 kg (I translated it into a pressure of 7798 pa, as the load is divided on a surface of 1 m long for 0.302 m wide). as maximum deformation I get 3.7 mm.
thank you so much to those who will have the time and the desire to help me and apologize if maybe I opened a post with a request that for many is more than banal.
