    i need the model dimensions and neoprene properties to compare the experimental results with the software result

    please send the details........

      The experimental data was performed in uniaxial compression using ASTM-sized specimens. What else do you need to know, and why?

        uniaxial compression of soft bodies

        first i like to thank for the reply
        i have taken solid cylinder of 80mm dia and 160mm length.
        material neoprene
        Neoprene Material Properties

        shear modulus= 0.0272 MPa
        poissons ratio= 0.499
        density= 960 kg/m3
        youngs modulus, E= 0.0815456 MPa
        Bulk modulus, K= 13.59093333 MPa
        Incompressibility parameter, d= 0.147156928

        iam doing analysis with ansys software(uniaxial compression of soft bodies).
        iam cnsidering the experimental results to compare with the software result with different material models like
        Yeoh Model
        Mooney-Rivlin Model (2 parameter)
        Arruda-Boyce Model
        Neo-Hookean

        i have to know ASTM standard size for uniaxial compresssion test. neoprene propertis if possible

          I don't recall the specimen size on top of my head, but the diameter was about 25 mm, and the height was about 12 mm.

            help

            hi and tanx
            plz tell me about density of this material or other
            because I research about vibration of viscoelastic material and need the densiti and modul of elsticity in liniar range

              The density was about 1000 kg/m^3.

                NEoprene

                thanks for your help,

                i was finding the material model for the new material. i gone through curve fitting technique and got the result.

                with regards,

                  Im working on the vibration of viscosolid
                  plz give me experimenta l data about shear and bulk and or elasticity module
                  or tell me abuot convert ur result to this result and give them to ANsys

                      Help!!

                      With reference to the above .zip file, I am in need of experimental data or coefficients for Neoprene 55-60 Degrees Shore Hardness. I am using CalculiX and have post-processed the problem in question. I have used C10 = 212 KPa, C01 = 48 KPa but I believe this to be for a Neoprene with a Shore Hardness of around 40 Degrees.

                      Thank you in advance.

                        Can you tell me what the units are for each of the three columns in your .txt files?

                        Thank you

                          Good question.

                          Column 1: Time in seconds
                          Column 2: True Strain
                          Column 3: True Stress (MPa)
