According to Von-Mises' distortion energy theory, the distortion energy under three dimensional stress state is represented by
-
-
1 [σ²1 + σ²2 + σ²3 - 2m(σ1σ2 + σ3σ2 + σ1σ3)] εE -
1 - 2μ [σ²1 + σ²2 + σ²3 - 2m(σ1σ2 + σ3σ2 + σ1σ3)] 6E -
1 + μ [σ²1 + σ²2 + σ²3 - 2m(σ1σ2 + σ3σ2 + σ1σ3)] 3E -
1 [σ²1 + σ²2 + σ²3 - 2m(σ1σ2 + σ3σ2 + σ1σ3)] 3E
-
Correct Option: C
| [σ²1 + σ²2 + σ²3 - (σ1σ2 + σ2σ3 + σ3σ1)] | |
| 3E |
