This paper presents a series of approaches for discrete time-domain synthesis of conical bore instrument sounds. The generation of steady, selfsustained oscillations using conical waveguides is complicated by properties inherent to truncated conic frusta. Two different physical structures are discussed which can be characterized by the same circuit diagram. A more abstract and flexible “virtual...

Vibration behavior of different types of porous functionally graded (FG) conical sandwich shells are investigated based on a modified high order sandwich shells theory for the first time. Sandwich shell includes FG face sheets covering a homogeneous core and the second one includes homogeneous face sheets and a FG core. Power law rule modified by considering two types of porosity distributions ...

Using an asymptotic integration method, this paper investigates the axisymmetric problem of elasticity theory for inhomogeneous transversal-isotropic truncated cone small thickness. It is believed that moduli are arbitrary continuous functions opening angle. assumed lateral part free stresses, and boundary conditions set at ends cone, leaving it in equilibrium. Homogeneous solutions have been c...

A truncated conical beam model is developed to study the vibration behaviour of a rat whisker. Translational and rotational springs are introduced to better represent the constraint conditions at the base of the whiskers in a living rat. Dimensional analysis shows that the natural frequency of a truncated conical beam with generic spring constraints at its ends is inversely proportional to the ...

Abstract The influence of single and multiple imperfection cases on the load carrying capacity mild steel cone subjected to axial compression was considered through numerical simulation in current paper. Three different techniques were considered, which are: i) uneven length (sinusoidal/square waves), ii) crack, iii) indentation (SLI) imperfection. Abaqus 6.19 FE used carry out simulation. comp...
