{"Image DocumentName": "And here comes the idea of Cosserat brothers", "Image ImageDescription": "Besides the force-stress tensors [Pa] there are also couple-stress tensors [Pa m] taken into account when the equilibrium conditions are considered. The Cosserat continuum is usually only effective when there exists a physical motivation for adding couple stresses and microcurvatures as is the case in granular materials. For a numerical implementation of Cosserat continuum see Sluys and de Borst. See Stein, E., de Borst, R., Hughes, T.J.R.: Encyclopedia of Computational mechanics, Vol. 2, p Eug\u00e8ne-Maurice-Pierre Cosserat (4 Mar 1866 \u2013 31 May 1931) was a French mathematician and astronomer. Born in Amiens, he studied at the \u00c9cole Normale Sup\u00e9rieure from 1883 to He was on Science faculty of Toulouse University from 1889 and director of its observatory from 1908, a position he held for the rest of his life. He was elected to the Acad\u00e9mie des Sciences in His studies included the rings and satellites of Saturn, comets and double stars, but is best remembered for work with his engineer brother Fran\u00e7ois on surface mechanics, particularly problems of elasticity.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
