8. A method of forming a downhole tool, the method comprising:
providing a first downhole component made from a brittle material and including a longitudinal axis, the first downhole component comprises a fracture toughness K1C lower than 20 MPa·m1/2, and a second downhole component including a first connection feature; and
connecting the second downhole component to the first downhole component with a connection member formed from a shape memory material and comprising: an outer surface including an outer diameter; an inner surface including an inner diameter, one of the inner diameter and the outer diameter modifiable by applying a stimulus to the shape memory material; and a second connection feature, complimentary of the first connection feature, formed on one of the outer surface and the inner surface, the connection formed by securing the connection member to the first downhole component at a corresponding surface of the one of the inner diameter and the outer diameter and connecting the connection member to the second downhole component via the first connection feature and the second connection feature to connect the second downhole component to the first downhole component.
