IMPLEMENTATION CHALLENGES FOR HIGH-TEMPERATURE COMPOSITES

FIGURE 12 FEM calculations for a drum rotor with a TMC annulus. The debonded regions within the TMC, caused by the transverse loads, are indicated on the right, while the hoop stresses in the TMC are on the left. Note that debonding has elevated the hoop stresses in neighboring regions of the TMC. These stresses would cause premature failure.

FIGURE 13 The shakedown and ratchetting regions in a TMC subject to transverse loads, σT, and cyclic temperature, ∆T: here, σo is the matrix yield strength. SOURCE: Reprinted (modified) from Jansson and Leckie (1994) [32], copyright 1994, with permission from Elsevier Science.
