Hello I am these days busy with designing a wheel using FEA. I use a steel where yield strength of 235 MPa and UTS of 340 MPa. According to FEA, I see some regions with stresses above 235MPa (somewhere around 240 MPa) and those regions are moved to elastic-plastic region. In rim designs what is...

I would like to know the range to be maintained, in LIFT RATIO design parameter of a tire, to overcome seperation. ( The ratio between the mean carcass diameters of cured tire, and the mean carcass diameter on building drum) Sriwardene

I need to know the reason of post curing inflation (PCI)of a tyre. (Keeping the tire on a rim under pressure for cooling, just after removing from the mould) How do we decide the time,temperature and pressure on PCI/ I was told that the tire needed to be kept on post curing inflator until...

Its a 3D solid model with a carcass defined by hypoelastic rebar properties and tread/sidewall with hyperelastic Van der Waal coefficents.

I have developed a FE model in ABAQUS platform to simulate stress/strain behaviour of a multi piece rim subjected to a radial load. Model is a rim/tire assembly with axisymmetric element. I used a finer mesh for the rim and a somewhat coaser mesh for the tire, since I was only focusing on the...

If a structure (eg: a tire) been subjected to an impact, and a static force (with a plunger)until it fails, Which failure energy be higher, or will they be same. ( Impact force will also be applied using the same plunger to the same position) If one is different from the other ; Why or How ...

In modeling of radial and axial deformation of tires, I basically look into von misses stress on critical areas in the tire,and most of the times, I do comparisons of mises stresses in different proposals than sticking into their magnitudes. I would like to know whether there is any predominant...
