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...

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...

Yes I mean tension strength, Thks!

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...

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...

run Ansys8 with Windows Vista? Thks Giamma

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...

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!

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

Thanks Garry, I have already take a look at matweb, but without results.....have you more ideas? giamma

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

Hi, where can I find informations about AW 6056 (tensile strength, yield strength....)

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?

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...

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?

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

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!!

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...

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

I'm using 6082-T4 as starting material for forging
