Investigation of Stress-Strain Behavior of Plastic Concrete Using Monotonic Triaxial Compression Tests

In this paper, the mechanical behavior of plastic concrete being used in the cut-off walls of earth dams has been studied. To do the task, triaxial compression tests on the specimens in various ages and mix designs under different confining pressures have been done and the stress-strain behavior of such materials and their strength parameter changes has been experimentally investigated. It has ...

Bladder tissue passive response to monotonic and cyclic loading.

The fundamental passive mechanical properties of the bladder need to be known in order to design the most appropriate long-term surgical repair procedures and develop materials for bladder reconstruction. This study has focused on the bladder tissue viscoelastic behavior, providing a comprehensive analysis of the effects of fibers orientation, strain rate and loading history. Whole bladders har...
