Abstract:

ITM09, Mounting flat fracture
The fracture appears to be a clean "clamshell" with no residual fracture lines propagating into the test mass. Analysis indicates that the Suspension ear will lie entirely below the void. The mounting flat was tested for residual stress and flatness and found to be compliant with existing specifications. See T1400711 for stress and flatness measurements.
