This paper presents a finite element based method to investigate the hygrothermal effects on the transient dynamic response of delaminated composite conical shells with initial twist impacted at arbitrary locations by multiple spherical impactors at a predefined time-delay. An eight-noded shell element has been used in the present analysis based on the Mindlin's theory. The multi-point constraint...
This paper presents a finite element based method to investigate the hygrothermal effects on the transient dynamic response of delaminated composite pretwisted conical shells with initial twist impacted at arbitrary locations by multiple spherical impactors. An eight-noded shell element has been used in the present analysis based on the Mindlin’s theory. The generalized dynamic equilibrium equation...
Optical filters using ring resonators made of silicon on insulator (SOI) based waveguides are enabling technology in the ever expanding field of optical communications. In this work series coupled four rings of two different radii have been used to expand the free spectral range (FSR) on the basis of Vernier principle with two SOI waveguides of different refractive indices (1.7 and 2.5). The quadruple...
