The BEM is a new method of numerical calculation compared with other methods. It has many advantages, such as smaller orderofequation, less data input, less internal storage and faster velocity .
On one side of the equation are the calories we consume. Onthe other side are the calories we burn — through physical activity aswell as whatever is needed just to keep the body in good working order.
In this paper, the initial-boundary value problem of a kind of nonlinear fourth-order wave equations with damping and source terms is studied on the base of Beam equation.
