1. A method of designing a golf club head by using a computer, comprising the steps of:

  • preparing a ball model and a club head model obtained by dividing a golf ball and a golf club head into a plurality of finite elements respectively, wherein said club head model is provided with a central reinforcing rib formed at a central portion of a rear surface of a face part thereof and a plurality of belt-shaped reinforcing ribs extended radially from said central reinforcing rib toward a peripheral edge of said rear surface of said face part;

    executing simulation of collision between said ball model and said club head model at a plurality of positions of a front surface of said face part thereof to determine a Mises stress generated at each of said collision positions; and

    changing setting conditions of said central reinforcing rib and said belt-shaped reinforcing ribs to set a maximum value of Mises stresses generated at off-center positions of said front surface of said face part to less than 1.3 times a maximum value of a Mises stress generated at a center of said front surface of said face part.
