Abstract:
This paper presents a new approach to the problem of determining the frequencies and mode shapes of Euler–Bernoulli tapered cantilever beams with a tip mass and a spring at the free end. The approach is based on the replacement of the flexible beam by a rigid multibody system. Beams with constant thickness and exponentially and linearly tapered width, as well as double-tapered cantilever beams are considered. The influence of the tip mass, stiffness of the spring, and taper on the frequencies of the free transverse vibrations of tapered cantilever beams are examined. Numerical examples with re

Abstract:
In this paper, the improvement of the performance of the piezoelectric (PZ) cantilever beam using the non-uniform substrate thickness has been presented. This reduces the resonant frequency, improves stress distribution and generates more output voltage and power. Both analytical and finite element method (FEM) analyses have been performed to investigate the effect of tapered substrate thickness on the PZ cantilever beam. The tapered substrate thickness has been used in rectangular and trapezoidal cantilever structures. All the designed cantilever structures have the same fabrication area, and

In this paper, the free vibration of a nonlinearly tapered cone beam is analyzed based on the Euler–Bernoulli hypothesis. The characteristic/eigenvalue equation and mode shape functions of the nonlinearly tapered cone beam are derived by the Adomian decomposition method for the first time. Using a modified mathematical procedure, the natural frequencies and mode shape functions of a general nonuniform beam are analytically derived. Several numerical examples for the vibration of uniform and linearly tapered cantilever beams are presented and compared with previous results to validate the accur

Problems related to the transverse vibration of a rotating tapered cantilever beam with hollow circular cross-section are addressed, in which the inner radius of cross-section is constant and the outer radius changes linearly along the beam axis.

Different continuous variations in the inertia are considered in achieving cantilever tapered beams to match functional design and resistance requirements. In this investigation, the expressions of linear and cubic variations in the inertia are associated to a linear mass distribution.

Abstract In stress corrosion studies, crack velocity plotted with respect to stress intensity generally yields a characteristic curve with three distinct regions. The first region (stage I) exhibits a threshold (KISCC) followed by a rapid increase in crack velocity (da/dt) for small changes in stress intensity. The second region (stage II) is characterized by an essentially constant crack velocity with increases in the stress intensity. The third region (stage III) exhibits a rapid increase in crack velocity for small increases in stress intensity leading to fracture. Stage I behavior has been

Abstract Cantilever is one of the most popular structures employed for vibration-based piezoelectric energy (PE) harvesters due to its simplicity in mathematical modeling and manufacturing.
