Embodiment Construction
[0066] Embodiments of the high cycle multiaxial fatigue life prediction method based on the weighted average maximum shear stress plane according to the present invention will be described below with reference to the accompanying drawings. Those skilled in the art would recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Also, in this specification, the drawings are not drawn to scale, and like reference numerals denote like parts.
[0067] The high-cycle multiaxial fatigue life prediction method based on the weighted average maximum shear stress plane includes the following steps:
[0068] Step 1): Obtain the load history of the notched parts, such as Figure 2a Shown, F N is the loaded axial force, M T For loading to torque, the load history of the...
