ANALYSIS OF COMPOSITE PIPE

Finite Element Analysis (FEA) is a computer-based numerical technique for calculating the

strength and behaviour of engineering structures. It can be used to calculate deflection, stress,

vibration, buckling behaviour and many other phenomena. It also can be used to analyze either

small or large-scale deflection under loading or applied displacement. It uses a numerical

technique called the finite element method (FEM). 

In finite element method, the actual continuum is represented by the finite elements. These

elements are considered to be joined at specified joints called nodes or nodal points. As the

actual variation of the field variable (like displacement, temperature and pressure or velocity)

inside the continuum is not known, the variation of the field variable inside a finite element is

approximated by a simple function. The approximating functions are also called as interpolation

models and are defined in terms of field variable at the nodes. When the equilibrium equations

for the whole continuum are known, the unknowns will be the nodal values of the field variable.
