Article Citation - Scopus: 5A Computer-Controlled Triaxial Test Apparatus for Measuring Swelling Characteristics of Reconstituted Clay-Bearing Rock(2008) Bilir,M.E.; Sari,D.; Muftuoglu,Y.V.To avoid problems encountered during and after the construction of engineering projects built within swelling rocks and soils, real data related to swelling stress and strains should be used to model such phenomena. A computer-controlled triaxial swelling test apparatus was developed to determine the swelling potentials for rock and soil specimens. It allows one to measure three-dimensional swelling strains and stress in a cylindrical specimen under variable axial and confinement stress variables. Triaxial swell tests were performed using three different procedures: free swell, strain-controlled, and stress-controlled under different axial and confinement stress conditions. The results of several tests conducted on reconstituted clay-bearing rock samples were statistically analyzed and mathematical models were presented and evaluated.

Saraloglu; Karakaya, Ishak; Konca, ErkanInternal stress in plated deposits has been a common problem that may affect the functionality of coatings. Electrodeposition parameters and insoluble particles modify the characteristics and the level of internal stress of coatings. The influence of the electrocodeposition parameters and their interaction effects on the internal stress during the electrodeposition of Ni and Ni-MoS2 composite coatings were studied by fractional factorial design. The parameters studied and their ranges were: MoS2 particle concentration (0-10 g L-1), temperature (30-50 degrees C), pH (2-4), current density (1.2-4.8 A dm(-2)), and coating thickness (25-50 mu m). MoS2 addition into Watts bath resulted in the decrease in the tensile internal stress values or even changed the stress character from tensile to compressive. Moreover, low stress values were obtained when pH was 2 and coating thickness was 50 mu m.
