Growth-induced instabilities are ubiquitous in biological systems and lead to diverse morphologies the form of wrinkling, folding, creasing. The current work focusses on mechanics behind growth-induced wrinkling an incompressible annular hyperelastic plate. governing differential equations for a two-dimensional plate system derived using variational principle with no apriori kinematic assumptio...

in this paper, a nonlinear free vibration analysis of thin annular functionally graded (fg) plate integrated with two uniformly distributed actuator layers made of piezoelectric (pzt4) material on the top and bottom surfaces of the annular fg plate is presented based on kirchhoff plate theory. the material properties of the fgm core plate are assumed to be graded in the thickness direction acco...

This study presents the effect of vertical and horizontal oriented cracks on free vibration response for circular annular thin plates. To investigate dynamic behavior damaged structures are modeled separately considering horizontal/vertical orientations, ten different locations, four crack sizes. For plates, placed in middle between outer inner edges to directions. The first five resonant frequ...

A one-year-old neutered male cat was referred for a grade IIIA open radius and ulna fracture. The mid-diaphyseal radial and ulnar fractures were associated with lateral radio-humeral and radio-ulnar dislocations. From these abnormalities, a diagnosis of type IV Monteggia fracture was made. The annular ligament was found to be intact on examination and the radial head was correctly positioned an...

A numerical method is presented for determining the static charge distribution and capacitance of a round disk capacitor. Based on equivalent surface charge distributions, an integral equation subject to the boundary conditions is transformed into an algebraic equation by using the method of moments. In the proposed scheme to eliminate the discretizing errors often encountered in other techniqu...
