Shape memory alloy reinforced casing

A casing for a bearing of a gas turbine engine including a shaft extending along an axial direction, the casing comprising:

• an attachment feature at a radially outermost portion of the casing, the attachment feature configured to be coupled to a static structure of the gas turbine engine;
• a plurality of support arms extending from the attachment feature to a radially innermost portion of the casing;
• and
• a shape memory alloy material disposed adjacent to a radial gap, the radial gap extending between the radially innermost portion of the casing and the bearing.

A casing for a bearing of a turbomachine including a shaft extending along an axial direction, the casing comprising:

• an attachment feature at a radially outermost portion of the casing, the attachment feature configured to be coupled to a static structure of the turbomachine;
• a plurality of support arms extending from the attachment feature to a radially innermost portion of the casing;
• a bumper at a radially inner surface of the casing, the bumper configured to define a radial gap between the bumper and the bearing;
• and
• a shape memory alloy material.
