Abstract: The energy required to roll a sphere in a cylindrical groove is shown to be partly a hysteresis loss and partly a microslip loss. Data for three different sphere-groove combinations are ...

Abstract: The calculation of Young’s modulus of an elastomer is based on the optical measurement of the contact between a transparent spherical indenter and the elastomer. The technique is based on ...

Abstract: The force necessary to roll a ball on a flat plate is experimentally determined as a function of the load for a number of different ball diameters and steel structures. Previously published ...
