Abstract:

Based on the force network ensemble theory, a general form of probability density function for force network ensemble is formulated in two different kinds of force phase space. Direct integration method and fourier transform method are proposed to solve the integral problem of probability density function.By comparing this two methods, it’s indicated that they all can solve this problem effectively,and the direct integration method is more convenience when K is small,while the fourier transform method has an advantage when N is small.
