Contact Stress and Wear Study for Type Characters

by F. I. Chow, P. A. Engel, D. C. Heath, S. Lawphongpanich
To ensure the structural integrity of solid print characters subjected to millions of stress cycles, the contact stresses encountered in service must be known. In the present paper various type geometries are explored for their influence on stress distribution. A linear programming method of stress analysis is adopted. Experimental analysis and wear characteristics are considered.
