Hyperelastic material constants

Question asked by 1-CTHJXY on Feb 23, 2010

Help. I'm new to this forum. I've done basic FEA of rigid plastic and metal components but am using NEI Works to do some analyses of molded silicone rubber parts. I need hyperelastic material constants. I've attached a screen capture of what input it's asking for. Can anyone help me with generic molded silicone rubber constants to put in here? I'm a lowly designer, not an engineer, so, sadly, I don't know what any of these are. I rely on pre-made material databases for stuff and I don't know where to look for this or what they are.
