I need to find a material that they use on undercarriages and has a high young's modulus (modulus of elasticity). Atm i have one at 93Gpa but it doesnt do the job.

appreciate the help if any of you are in this area

    You...may have difficulty finding someone on here who knows this. I know it's probably a shot in the dark and all, but it's also a pretty obscure question for a forum related to Gaming and such.

    Heck, I work in the aerospace field and I haven't the slightest clue what a "high young's modulus" is. Then again, I'm not an Aerospace Engineer or anything, so perhaps that's why.

    All I can really help you with is that typically most aircraft undercarriages utilize magnesium alloys quite a bit, though that's more for it's strength to weight ratio and its resistance to corrosion. Having no idea what you've currently tried to use so far though, I really don't know what else to suggest.

    Sounds like this is where I come in.

    As a matter of fact, magnesium and titanium alloys are typically used in aircraft for their high Young's Modulus. I'll go dig up my old Strength of Materials text and see what I can find, though off the top of my head titanium has about the 93 GPa you're rocking right now.

    EDIT: Young's Modulus, better known as modulus of elasticity. Umm... Ti-6A1-4V has a modulus of 120 GPa. Other than that, your best bet for strength to weight is probably something carbon fiber composite or similar; Kevlar plastic has about a 131 GPa modulus.

    If you're not concerned with weight, go with a steel alloy. Structural A36 has 200 for not quite twice the density of titanium, and Tool L2 is similar.
