    Laser resistant material

    Hello, I need a material that could be resistant against a 3000nm Erbium laser or a CO2 laser. I would like to use that material as a thin film stencil on a curved surface, and to cut everything outside it. If you have ideas of materials or methods to do that, please let me know. Thanks

    Hello, I am doing a static linear analysis on an assembly made of 3 parts as shown in the simplified drawing that I attached. I am running this assembly in two different scenarios : 1st- Interface AC is glued and ED is glued. 2nd- Interface BC is glued and BA in contact but not glued, ED is...

    control metallic ball coordinates by magnet

    Hello, I have zero knowledge in the electromagnetic engineering field, and I would like to know if you can help me in the following question : Is there a device or a method that allows us to control the position of a small metallic ball ? For example, the ball initial position is at x=0 y=0...

    Binding two carbon fiber ends

    Hello, The question might be a bit more in the materials field . Is there a way to join two ends of carbon fiber? I know that you can bond them together, but if we do that, will the properties of the joint be the same as the other locations of the 2 pieces or will it be weaker? Whats the best...

    fea on an anisotropic ring

    I have a simple ring,made of an anisotropic material (unidirectional fibers )that I would like to study in femap. If I use the material type as "anisotropic" in femap, I will be able to insert the young modulus in X,Y and Z . I understand that if it was a bar or a straight object,it would be...

    anisotropic material

    I know that this question may sound very stupid , but if I know the Young modulus in the X,Y and Z directions of an anisotropic material, how can I get the elastic matrix (G) ? (XX YY ZZ XY YZ ZX) For example : Young modulus in X = 39 GPa , Y= 12 GPa, Z= 12 GPa. thank you .

    ramp load

    Hello, I have a very simple assembly containing a cube and a sphere. The two models do not touch in the beginning,they are 1 unit(or 1 cm) far from each other. I want that the cube be fixed , and then apply a force and a motion in one direction(like the x axis) on the sphere that will increase...

    Problem with static structural analysis

    Hello, I recently started using femap 11.1 and I've been having a problem for the past two weeks that I can't solve. I have a simple assembly of two parts that I exported as a parasolid ( .x_t) from solidworks. When I run the FEA static analysis in solidworks simulation , it works with no...
