Abstract The aim is to derive an expression calculate the natural frequencies and plot mode shapes of a simply-supported beam with overhang end point mass by using Euler-Bernoulli theory in case free transverse vibrations. results are validated finite element analysis. importance system presented that it can represent machine tool spindles or even machining tools like boring bars. good agreemen...
In this paper, dynamic instability due to parametric and external resonances of moderately thick functionally graded rectangular plates, under successive moving masses, is examined. Plate mass per unit volume and Young’s modulus are assumed to vary continuously through the thickness of the plate and obey a power-law distribution of the volume fraction of the constituent. The considered rectangu...
linear dynamic response of simply supported nanobeams subjected to a variable axial force is assessed by galerkin numerical approach. constitutive behavior is described by three functional forms of elastic energy densities enclosing nonlocal and strain gradient effects and their combination. linear stationary dynamics of nanobeams is modulated by an axial force which controls the global stiffne...
