This research aimed to investigate the stress-strain-strength behavior of the Ipanema Beach (RJ) sand in direct simple shear tests (DSS) carried out on dry specimens, sheared at constant volume under strain-controlled static loading. A procedure for preparing dry sand specimens was developed for DSS tests. The specimens were prepared in loose, medium, dense and very dense domains of relative density (Dr). For each of these Dr domains, DSS tests were carried out under the following initial vertical stress values: 25, 50, 100, 150, 300, 500 and 750 kPa. The results allowed to evaluate the influence of the initial vertical stressand the pre-shear void ratio (epc) on the vertical stress change (variation of vertical stress in shear) necessary to keep the specimen height (and volume) constant during shear, on the rate ofmobilization of the friction angle in the horizontal plane in relation to distortion, on the value of the maximum friction angle mobilized in the horizontal plane, on the value of the shear stress at failure, on the value of the distortion at failure, as well as on the values of the secant shear modulus G25and G50.
