The NASTRAN constraint set acts on the DOFs in the output coordinate system (not the definition coordinate system). If you are aligned with the global coordinate system, you just constrain the out-of-plane translation. If you are not aligned, you will need to define a local coordinate system...
The finite element method uses a strain-displacement matrix where the calculated nodal displacements are used to calculate strains at the gauss points. Stresses at the gauss points are calculated by multiplying the gauss point strains by the elasticity matrix. The nodal stresses are typically...
If you are having a problem finding work as an entry-level EE, don't you think you will also have a problem finding work as an entry-level EE Engineering Manager? Certainly, the number of job opportunities for technical EE's must be significantly greater than the number of job opportunities for...
What if we were to develop a method to identify the "best" automobile? We could define a course, say off-road, highway, city, etc., define different loads, like towing, hauling materials, hauling people, etc., and define different criteria, like cost, gas mileage, acceleration, emissions...
