| 41. | HSS makes up 59 % of vehicle body mass; 1, 500 MPa yield strength steel makes up 7 %.
|
| 42. | At that point the bolt has a preload determined by the bolt area and the yield strength of the bolt material.
|
| 43. | For perfectly brittle materials, yield strength and ultimate strength are the same, because they do not experience detectable plastic deformation.
|
| 44. | Thus, there is then an inverse relationship between grain size and yield strength, as demonstrated by the Hall Petch equation.
|
| 45. | However, as the normal force increases, eventually the stresses in the plate's surface will exceed its yield strength.
|
| 46. | The formed tube is then cooled and can be cold worked to refine the diameters and to achieve the desired yield strengths.
|
| 47. | The hull is constructed of high tensile steel with a yield strength of S355 N / mm?structural steel grades '.
|
| 48. | The ferritic structure and alloy additions, such as nitrogen provide yield strengths that are twice that of 300 series stainless steels.
|
| 49. | In addition, structures are required to be of an acceptable strength, which is related to a material's yield strength.
|
| 50. | Let a material have a yield strength \ sigma _ Y and a fracture toughness in mode I K _ { IC }.
