Discontinuities in material resistance
Discontinuities in material resistance
(OP)
Could somebody explain me what is a discontinuity in material resistance so I can modelize curve beam and plates in finite element?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

"Reduced-stiffness" in method (c) means you toggle, e.g., elastic modulus E of the interface elements to simulate any amount of fixity desired in the connection, from nearly free (like "rubber") to semi-rigid to completely rigid. Reducing moment of inertia I in the interface elements reduces bending stiffness; reducing area A reduces axial stiffness; reducing E reduces bending and axial stiffness. Axial stiffness is EA/L. Bending stiffness is EI/L. Good luck.
