Increased force necessary for operating the pedal is due to hardened springs of the clutch, or — if your vehicle has a hydraulic-assisted clutch activation — because of a malfunction in the hydraulic system.
Movement of the tibia was generated by the coordinated activation of two hydraulic cylinders, one to simulate quadriceps muscle force, and the other to apply external flexion moment.
The tibia was moved by the coordinated activation of 3 hydraulic cylinders, which were attached to the specimens' tendons by special clamps, one to simulate quadriceps muscle force, one to simulate a co-contraction of the hamstring muscles, and the third to apply an external flexion moment.
The activation of natural fractures during hydraulic fracture treatments improves fracture complexity and expands reservoir drainage area, making stimulation treatments more effective.
We conducted three-dimensional coupled fluid-flow and geomechanical modeling of fault activation and seismicity associated with hydraulic fracturing stimulation of a shale-gas reservoir.
In shale formations, non-planar, complex hydraulic fractures are often observed, due to the activation of pre-existing natural fractures.
During the large-scale hydraulic fracturing process, there is reactivation of preexisting (cemented) natural fractures and activation of planes of weakness, and even connected with hydraulic primary and secondary fractures, which is so-called fracture networks or stimulated reservoir volume.
