## 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.
