Abstract

<abstract abstract-type="main" id="nag2342-abs-0001"> <title>Summary</title> <p id="nag2342-para-0001">We investigate the elastic behavior of weakly cemented contact. We show that the radial distribution of stresses and the stiffnesses of a cemented contact are governed by the ratio <italic>a</italic>/<italic>R</italic>Λ, where <italic>R</italic>, <italic>a</italic>, and Λ are, respectively, the grain radius, the contact size, and the ratio of the elastic moduli of cement and grains. Moreover, we show that a cemented contact is always less stiff than a Hertzian contact having a similar size. Finally, we propose accurate approximate expressions of the contact stiffnesses.
