| 41. | Typical brittle materials like glass do not show any plastic deformation but fail while the deformation is elastic.
|
| 42. | Plasticity surface friction is also very low in comparison to the plastic deformation energy and can be neglected.
|
| 43. | In addition, when the stress is independent of this strain rate, the material exhibits plastic deformation.
|
| 44. | A shear instability arises when heat is produced by plastic deformation faster than it can be conducted away.
|
| 45. | Excessive contact pressure can lead to a typical bearing failure such as a plastic deformation similar to peening.
|
| 46. | These materials do show viscous flow is the dominant source of plastic deformation, and is also very slow.
|
| 47. | One proof is to match the broken halves, which should fit exactly since no plastic deformation has occurred.
|
| 48. | This is important because plastic deformation raises the temperature of the oil or lubrication fluid and changes the viscosity.
|
| 49. | Plastic deformation induces a residual compressive stress in a peened surface, along with tensile stress in the interior.
|
| 50. | Another con is that this plastic deformation can cause corresponding high points in the shaft surrounding the circular mark.
