    thermosets fem analysis

    Hi to everybody, I have to make a static structural analysis of a shield of a electric motor made of thermoset. I cannot know the orthotropic data about this material and I have to develop the simulation considering the isotropic characteristics. Has someone a suggestion? Is this simulation...

    thermal condition

    Hi to everybody, I have a shaft with a fan forced-fit ( steel for the shaft and plastic for the fan), I have to consider a thermal load of 130°C because the assembly (fan+shaft)work at these temperature and I want to evaluate if the fan remain fit(with the contact tool). I consider only 1/4 of...

    failure criteria for brittle materials

    Hi to everybody, I have to develop a FEM structural analysis of a part made of a plastic substance. this substance has a different behaviour between traction and compression (the ultimate traction strength is about 1/3 of the ultimate compression strength). I think that the Mohr-Coulomb failure...

    Principal Stress for plastic substances?!?!

    Hi to everybody, I have to develop a structural analysis of a plastic part; the material has different behaviour between compression and traction ( Rm(traction)<Rm(compression) naturally). I can't use Von Mises equivalent stress with this material, I think that I can use the principal stress to...

    plastic strain with straus7

    already done....but the difference is too little ( 0.0002 mm )....the yeld strenght is 276MPa ( aluminium 6061 T6 with Ramberg-Osgood non linear behaviour ) and the compression load is 300MPa...the compression test done in a laboratory give about 0.06 mm of plastic deformation ( with initial...

    plastic strain with straus7

    hi to everybody! I'm using straus7 and I have to simulate a compression test, but how can I estimate the elastic strain and the plastic strain separately?The software give the total strain but I need the plastic strain only (when applied loads are removed). thanks!

    young modulus for aluminium

    Hi to everybody, I have a question: how change the young modulus of an aluminium alloy in consequence of work-hardening? thanks

    Ansys data base

    hi, I need the database of aluminium alloys for the fatigue module of Ansys 8.0, where can I find it? thanks

    &quot;orange peel effect&quot; in AW 6082 T4

    Thanks TVP, If I understand the situation, I have mistaken the treatment to obtain T4 state from O state. If I use a really T4 raw material, I will not have the orange peel effect/fracture....is it right?

    &quot;orange peel effect&quot; in AW 6082 T4

    I use wire (6082 O) with a length of several meters as starting stock, then i cut the wire and I make the T4 treatment (solution treatment of 530°C, quenching in cold water, then natural aging), after this treatment I use slugs for the tests of cold forging with a mechanical press SAKAMURA. I...

    how deformation affects the mechanical properties of aluminium cold fo

    Exist a correlation between work-hardening of aluminium alloys and their mechanical properties like yield and tensile strenghts? The cold forging of an aluminium alloy change its mechanical properties, but how? How change the yield/tensile strenght after cold forging?

    how deformation affects the mechanical properties of aluminium cold fo

    Hi, I need to find a correlation between cold forging of aluminium alloys and their mechanical properties. thanks!

    Where to find examples on fatigue simulations

    Hi, can anyone please tell me where to find ANSYS tutorials on fatigue? Have ANSYS 8.0 a fatigue module? I have to study the fatigue effect on an aluminium ( 6082 T4) anti-vibrating joint. thanks!!

    &quot;orange peel effect&quot; in AW 6082 T4

    Hi TVP, it's a bush, with covering of rubber, it's an anti-vibrating joint for automotive. It's a multistage cold forging process with 6 stages. The orange peel/fracture occurs after the second stage. You can find the composition of 6082 T4...

    alluminium alloy for a fork of steering-gear

    I have to choose the alloy for the forks. They are stressed (vibrations) and I don't think that AW 6082 is the better choice...maybe 8090 is better because the fatigue crack growth resistance is higher than that of the AW 6082 alloy
