Solid Mechanics: Stress
|
| Case 1: txy > 0 and sx > sy |
|
| The principal axes are counterclockwise to the current axes (because
txy > 0) and no more
than 45º away (because sx
> sy).
|
|
|
| Case 2: txy < 0 and sx > sy |
|
| The principal axes are clockwise to the current axes (because txy < 0) and no more than
45º away (because sx >
sy).
|
|
|
| Case 3: txy > 0 and sx < sy |
|
| The principal axes are counterclockwise to the current axes (because
txy > 0) and between
45º and 90º away (because sx < sy).
|
|
|
| Case 4: txy < 0 and sx < sy |
|
| The principal axes are clockwise to the current axes (because txy < 0) and between 45º and
90º away (because sx <
sy).
|
|
|
| Case 5: txy = 0 and sx > sy |
|
| The principal axes are aligned with the current
axes (because sx >
sy and txy = 0).
|
|
|
| Case 6: txy = 0 and sx < sy |
|
| The principal axes are exactly 90° from the
current axes (because sx
< sy and txy = 0).
