Hi everyone, I need an urgent help from all of you. I am doing a viscoelastic material simulation in radioss using kelvin maxwell law. i have the material data in storage modulus vs frequency so i changed my data into g(t) vs t. now when i go for curve fitting the value of prony term gi is coming greater than one.. As i have read in abaqus manual that value of gi should be less than 1 ,, so my question is this theory applied with radioss also or I can use my prony term coefficient which are coming greater than one.Please clear my concepts regarding this or also as per radios can i take the no of prny term more than 5 during curve fitting,, clear my concpts regarding this
Hello All, I have one rigid component and one elastic component (both are 2D). How can I connect these two components using 1D rigid elements? I am using Hypermesh with LS-Dyna interface. Thank you, Sriram
Hi, I was trying to introduce the mechanical properties for a composite component made of CFRP (Composite Fibre Reinforced Polymer). As I'm a beginner, I'm following the book Practical Aspects of Finite Element Simulation by Altair University. In there, I've found mechanical properties for many other materials, as I show in the image, but I can't find some general properties to define CFRP. Moreover, as it is an orthotropic material, I've learnt from the tutorials that I need to specify more data. Can anyone help me to find the general properties I need in the picture for MAT8 in order to define CFRP material? If possible, I'd like to see the reference for checking it up. Thanks in advance, Julio
