    Modelling the shear modulus of a material.

    Hi, I am trying to model the shear of a special composite material that I have designed. I have modeled a simple block. And simply applied a parallel force on the block. The procedure is i measure the resulted displacement and divide it by the initial length of the block. The problem i am...

    Calculating the Poisson's for a material ratio using percentages of strain at break.

    Hello I have been provided a data sheet for laser-sintered polyamide. It had the values for percentages of axial and transverse strain at break. I have tested the mechanical properties of the actual material, but i want to calculate the Poisson's ratio using the provided values in the data...

    Forces For stiffness Test

    drawoh, Thank you for your advice. __ Tmoose, I recieved the actual file in (.igs) format, and then i had to export it to (.stl) and added some features to it before sending the file to the SLS machine. And i tried changing the file fromat back to (.igs) or any other suitable format but it...

    Forces For stiffness Test

    btrueblood, I only have 2 samples manufactured and it is very hard to produce more, duo to financial reasons. That's why i wanted to get the most information from them as possible without destroying them. That is why i wanted to know if there is a way to even find an estimation of the...

    Forces For stiffness Test

    dhengr, Excuse me but, I have explained my case, and i dont have deep information in this area, otherwise i won't ask for advice. If you couldn't understand and you dont want to help that is fine, you are not obligated to. Just as much as i am not obligated to justify that i am an engineer to...

    Forces For stiffness Test

    drawoh, No, i cant feed the model into an FEA software duo to the file format (.stl). And yes, I will mount the physical manufactured part on a testing rig and apply a force and measure the displacement. My question is how can i determine the value of acceptable froces that can be applied into...

    Forces For stiffness Test

    drawoh, I can't do it computationally, it is a very complex shape and i only have it in .stl format. The part was manufactured using selective laser sintering machine, the core of the part is complex too (Lattice structure). I will do a physical stiffness experiment but i want to find the...

    Forces For stiffness Test

    Hi, I Have a nylon part that is made by laser sintering, the core of the part is a lattice structure, and i will do a stiffness test on it by applying a force and measuring the deflection. How can i determine the range of forces i can apply to the part without destroying it? Thanks
