    Can CalculiX simulate dynamic rubber seal compression?

    I am trying to simulate the deformation of a rubber seal. The seal is initially stretched over a groove, the initial deformation needs to be analysed. Then the outer diameter is compressed by a dynamic clamp, this deformation also needs to be analysed. I would like to do this all as a 2D...

    Pressure in compression molding

    What are the effects of pressure in compression molding, is it just there to stop the molding die top from lifting due to thermal expansion of the rubber in the tool or does it have any other advantages? Are there any calculations that can be made to determine which tool or component requires...

    Hot wire cutter used for plastics?

    We are currently looking into methods of cutting plastic rods with diameters being a typical maximum of 5mm, examples of some plastics are PEEK and PTFE. Could a hot wire cutter be used for this to get an accurate cut? If so, can this be done with a fairly thin wire diameter which would result...

    Rubber state of cure theory

    I am trying to understand how a rubber sample state of cure changes with time. Up to now I have created a temperature plot in which the temperature is known at each point within the rubber component however, I am having difficulty understanding how it cures. The information I have currently is...

    How long will it take for heat to flow through this sample?

    I have a rubber sample here, basically it is a slice with a diameter of 45mm and a depth of 3mm. If this sample was at 25 degrees Celsius and I applied 180 degrees temperature all around it (top, bottom faces and outside diameter) how long would it take for the centre point (last point to get...

    Can I import 2D CAD files directly into Patran?

    Hello, I am trying to simulate a 2D test case and was wondering if I could import 2D geometry from a 2D CAD software, when I looked inside of the import menu on Patran I only saw 3D import methods such as STEP, STL, Pro-Engineer, etc... Is this even possible or will I have to manually create...

    How does rubber cure physically?

    Hello, I am trying to simulate the curing of rubber but I am confused with how rubber actually cures in reality. From looking at rheometer results I can see that initially the viscosity of the rubber drops as it is heated, the rubber flows then the viscosity/stiffness of the rubber starts...

    Why do people use Visual Basics on Solid Edge?

    I see on forums all over the internet not just for solid edge but for other design software also people convert there parts into Visual basics and say it is used to change a part file into a text file, what is confusing me is...what is the point? why do you convert to visual basics? can you...

    Vehicle Drag Vs Down Force

    I am planning on designing/building a race car with the use of an aluminium frame and sheet metal to enter in a small contest, I am having trouble deciding how I should build the body, I read about aerodynamics and found that it is important to have a low Drag Coefficient so that there is very...
