TL;DR: In this article, a series of uniaxial compression tests were performed on specimens made of rock-like material, made of 72% silica sand, 16% cement (Type I) and 12% water by weight.
Abstract: To study the failure mechanisms of joints and rock bridges in jointed rock masses a series of uniaxial compression tests were performed on specimens made of rock-like material. Specimens of size 63.5 cm × 27.9 cm × 20.3 cm, made of 72% silica sand, 16% cement (Type I) and 12% water by weight were tested. The joint inclination angle was maintained at 45°, while the offset angle i.e. angle between the plane of the joint and the line that connects the two inner tips of the joints, was changed from 0°–120° with an increment of 15°. The tests were performed using a 2000 kN universal compression machine and a HP data acquisition system. In each sample, five LVDTs were fixed to measure the displacements along and across both the bridge and the joint segment, and the total displacement along the total length of the sample. The failure mechanism was monitored by visual inspection and a magnifier to detect cracks initiation. For each test the failure surfaces were investigated to determine the characteristics of each surface. In all of the tested samples curvilinear cracks called wing cracks initiated at the joints tips due to high tensile stresses concentration. These wing cracks were directed along the direction of the uniaxial load. The coalescence mechanism of two cracks was investigated. Results showed that open cracks could coalesce by shear failure or tensile failure. The coalescence path was found to be mainly dependent on the inclination of the rock bridge between the cracks.

TL;DR: In this article, the authors investigated the annual performance of multi-effect desalination plant combined with a thermo-compressor MED-TC driven by a solar steam generation plant and found that the solar field oriented along a north-south axis presents the best performance and the solar fraction does not increase significantly as the pressure of the saturated steam generated varies.

TL;DR: In this paper, the dual phase lag heat conduction model was used to study the transient temperature in a thin metal film exposed to short-pulse laser heating, and it was shown that zero temperature gradients at the boundaries within the framework of the dual-phase lag model does not imply negligible boundary heat losses unless the initial heat flux distribution is negligibly small.
Abstract: Transient heat conduction in a thin metal film exposed to short-pulse laser heating is studied using the dual phase lag heat conduction model. The initial heat flux distribution in the film, resulting from the temporal distribution function of the laser pulse, together with the zero temperature gradients at the boundaries normally used in literature with the presumption that they are equivalent to negligible boundary heat losses is analyzed in detail in this paper. The analysis presented here shows that using zero temperature gradients at the boundaries within the framework of the dual phase lag heat conduction model does not gcutrantee negligible boundary heat losses unless the initial heat flux distribution is negligibly small. Depending on the value of the initial heat flux distribution, the presumed negligible heat losses from the boundaries can be even way larger than the heat flux at any location within the film during the picosecond laser heating process. Predictions of the reflectivity change of thin gold films due to a laser short heat pulse using the dual phase lag model with constant phase lags are found to deviate considerably from the experimental data. The dual phase lag model is found to overestimate the transient temperature in the thermalization stage of the laser heating process of metal films, although it is still superior to the parabolic and hyperbolic one-step models.
