i know the answer but i wont tell u
permanent deformation in non crystalline materials is due to viscous flow or localized slip! deformation depends on glass transition temperature.
Strike-Slip Faulting
Strike slip faults display horizontal or "sideways" deformation.
fracturing, basal slip and plastic deformation or plastic flow :)
Stick-slip machines are designed to provide more controllable motion than a traditional electric motor. The basic design consists of a motor a control board and a stick-slip mechanism. The motor is used to provide the power to move the stick-slip mechanism while the control board is used to regulate the speed and position of the mechanism. The stick-slip mechanism consists of an elastic element such as a spring or rubber band that is connected to a shaft. When the shaft rotates the elastic element is compressed and then released creating a stick-slip effect. To design a stick-slip machine the following steps must be taken: Choose an appropriate motor and control board. Design the stick-slip mechanism and select an appropriate elastic element. Select the appropriate shaft and bearing system. Integrate the motor control board stick-slip mechanism and shaft into a single system. Test the system and adjust as necessary for optimal performance.By following these steps it is possible to design and build a reliable controllable stick-slip machine.
when a load act in a member, the structure will retain the load or deformation takes place whereas in mechanism it will not take the load. It will slide down without taking the load.
Shear forces are the responses of a rock to deformation usually by compressive stress. These forces form a strike slip fault.

A slip sheet machine. It is a forklift with very thin tines and a mechanism to push the freight off the tines onto the floor.
elastic deformation, ductile deformation and fracture
1-Slip occurs in distinct atomic spacing multiples, whereas the atomic displacement for twinning is less than the inter-atomic separation, usually proportional to their distancesfrom the twin plane. 2-for slip, the crystallographic orientation above and below the slip plane is the same both before and after the deformation; for twinning, there will be a reorientation across the twin plane.
