A thin circular ring of a rectangular cross-section is exposed to external pressure. Déterminez la charge critique et le facteur de charge correspondant pour le flambement dans le plan.
A vertical cantilever with a square cross-section is loaded at the top by tensile pressure. Le porte-à-faux est en matériau isotrope. Calculate the deflection.
A cantilever beam with an I-beam cross-section of length L is defined. The beam has five mass points with masses m acting in the X-direction. le poids propre est négligé. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
Montrer que le couplage de différents éléments dimensionnels n'affecte pas les résultats. A cantilever with a rectangular cross-section is fixed at one end and loaded at the other by concentrated forces. Neglecting its self-weight and assuming only small deformations, determine the cantilever's maximum deflections.
