direct shear stress is a strain – controlled test: the rate at which the soil will be strained is controlled. A specimen of soil will be placed into a shear box, and consolidated under an applied normal load. The shear box is made of two separate halves, an upper and lower. After the application of the normal load, these two halves of box will be moved relative to one another, shearing the soil specimen on the plane that is separation of the two halves. The direct shear test imposes stress condition

are Newtonian or Non-Newtonian materials. Parallel plate rheometer is preferred to adjust the shear stress and shear rate relationship of the specimens at 25°C and 70°C and test results are evaluated with the plotted flow and viscosity curves. Then, samples are categorized due to their time dependence or shear stress dependence. 1. INTRODUCTION A Newtonian fluid is a fluid whose stress versus rate of strain curve is linear and passes through the origin. The constant of proportionality is

Proposed codal provisions for design and detailing of beam-column joints in seismic regions Sudhir K. Jain, R.K. Ingle and Goutam Mondal Beam-column joint is an important part of a reinforced concrete moment resisting frame subjected to earthquake loading. Design and detailing provisions on beam-column joints in IS 13920 : 1993 do not adequately address prevention of anchorage and shear failure in this region during severe earthquake shaking. In view of these limitations, this paper proposes

how much the bar or specimen is twisting and at what angle. This test can also be done in reverse order measuring the angle first, and recording the torque on the test material. The testing of a “torque-angle” graph can be somewhat similar to a “stress-strain” curve. There are a few different types of torsion tests * Torsion only: applying only a torque (what we had done) * Axial-torsion: Applying and axial, as in tension or compression, and a torsion force to the specimen * Failure:
