Classical Rayleigh Ritz Method

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 »

Basics aspects in Finite Element Method (FEM)

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 »
