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.
Une plaque rectangulaire sur appuis simples est chargée de différents types de charge. Assuming only the small deformation theory and neglecting self-weight, determine the deflection at its centroid for each load type.
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.
Une barre de section carrée est fixée à l'extrémité supérieure. The rod is loaded by self-weight. For comparison, the example is also modeled with the concentrated force load, the value of which is equal to the gravity. The aim of this verification example is to show the difference between these types of loading, although the total loading force is equal.
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.
