Ujwalkumar D. Patil Anand J. Puppala Laureano R. Hoyos Aritra Banerjee Received: 18 May 2017 / Accepted: 26 May 2018 Springer International Publishing AG, part of Springer Nature 2018 Abstract A thorough analysis of strength, stiffness, equations, respectively. A thorough analysis and and stress-induced anisotropy of statically compacted modeling of stress-dilatancy behavior is presented in silty sand is presented based on results from a a companion paper. Finally, the inherent-anisotropy comprehensive suction-controlled (drained) triaxial observed in the original soil fabric, as well as the stress test program. Induced soil suction values, via either induced-anisotropy observed in the sheared samples, axis-translation or relative humidity techniques, are discussed based on results from suction-controlled ranged between 0.05 to 300 MPa, with net conﬁning isotropic consolidation and axisymmetric shearing, pressures varying from 100 to 300 kPa. A relatively respectively; including the effect of suction on the rate simple model/equation for peak friction angle (/ ), of degradation of stiffness (moduli) of compacted silty peak sand under monotonic shearing. over the entire test suction and net conﬁnement range, is presented. As expected,
