الملخص الإنجليزي

The spring constant of an infinite triangular network of identical springs is investigated within the framework of the lattice Green's Function and perturbed lattice.

Two perturbations are considered: the broken bond (missing bond) spring constant, and the two broken bonds (Two missing bonds) spring constant.

A connection is made between the spring constant and the lattice Green's Function of the perturbed network.

The spring constant of the perturbed lattice are expressed in terms of perfect lattice by solving Dyson's equation.

The spring constant between two adjacent nodes is calculated by corresponding equations and some recurrence formulae.

For an infinite triangular lattice, we used an expression for the spring constant in terms of lattice Green's Function at the origin, known as rational number, and some recurrence formulae.

Throughout this work, we found that the effective spring constant of the perturbed lattice in the case, one broken bond spring constant and two broken bonds spring constant, are greater than that of the perfect lattice.
