Classical Rayleigh Ritz Method Introduction: Classical Rayleigh Ritz Method is named after Walther Ritz and Lord Rayleigh and is widely used. Classical Rayleigh Ritz Method is a method of finding displacements at various nodes based on the theorem of minimum potential energy. Departure from classical Rayleigh Ritz Method leads to FEM. The two departures are: … Read more
Principle of Virtual Work and Minimum Potential Energy (P.E.) Introduction: The Total Potential Energy is nothing but the energy due to Strain Energy (internal work done) and Work potential of a force (external work done). Theorem of P.E.: Of all the displacements satisfying given Boundary conditions and Equilibrium conditions, the actual displacement is … Read more
FINITE ELEMENT METHOD (FEM) Introduction: Finite Element Method (FEM) is nothing but a numerical technique to get the approximate solution to the boundary value problems consisting of a partial differential equation and the boundary conditions. The Finite element Method converts these typical equations into a set of algebraic equations which are easy to solve. Basic … Read more
