  A Detailed Step-By-Step Procedure on Finding the Square Root of a 4 × 4 Positive Definite Symmetric Matrix for Engineering Applications

  By KNV CHANDRASEKHAR

  Abstract: The main focus of this study is to present a detailed step by step procedure to determine the square root of a symmetric positive definite non-singular matrix. The procedure involved four steps which are Gram–Schmidt orthogonalization, Schur form, U matrix, and square root of matrix, which are discussed in this study. Few examples are solved to learn and practice. Necessary checks were performed, and the results show that the square …

  Using Six-Node Hexagonal Elements to Perform Free Vibration Analysis of Laminated Composite Conoidal, Elliptical Paraboloid, and Hyperbolic Paraboloid Shells

  By KNV CHANDRASEKHAR, Uday Reddy

  Abstract: Laminated composite structures are one of the recent developments in the field of engineering with high strength and better cost-to-weight ratio over the isotropic materials. The present study is mainly focused on the free vibration analysis of laminated composite shells using six-node hexagonal elements which is the first one of its kind. Three different shells, namely conoidal, elliptical paraboloid and hyperbolic paraboloid, have been analyzed with different support conditions, and …
