Question

Q1) how to know a part fail in simulation in solid works ?

Q2) where does maximum tension and compression occurs at part in simulation ?

W

Q3) why we look at Von misses stress not at bending stress in simulation ?

Q4) what effect does fillets have on a part during simulation? Is it significant ?

Answer 1

Answer:

Simulation is defined as the imitation of the model to be developed including all its properties such as Physical structure , behaviour , key characteristics , properties , function.

1 . Failure in parts can be identified by the error shown in solid works or if it doesn't give the desired results .

Another method for determining failure is when the ductile parts in assembly of parts is below the value of yield strength half value i.e. FOS = 2 in bending and tension .

2 . Maximum tension and compression occurs at the

Maximum tension stress = maximum of 1st principal stress

Maximum compressive stress = minimum of 3rd principal stress

3 . Von mises stress has certain benefits in comparison to the bending stress , one of them is that it is able to predict certain yielding of the following material under complex loading situation.

4. Fillet creates the stress concentration on the region if used for weld assembly . However in cases of big assembly parts where we have to add or remove material , we can use fillets .
