الملخص الإنجليزي

The spring constant of an infinite network of identical springs is calculated in two-dimensional , using the Lattice Green’s function (LGF).

This work deals with two cases: the perfect lattice and the perturbed lattice (i.e.

a bond between two lattice points is removed and removing two bonds from the perfect lattice ) It is shown how to derive the basic formula which relates the spring constant to the LGF.

In calculating the spring constant we make use of the values of the LGF at arbitrary sites and we use some recurrence formulae.

The asymptotic behavior of the spring constant in a square for both the perfect and perturbed cases is studied.

The study resulted in finding that for a perfect lattice (i.e.

square lattice) the spring constant is symmetric along the low-index directions, whereas for the perturbed case the symmetry is broken.

We demonstrate that spring constant in a square lattice diverges as the separation between the sites increases value.
