MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611023983 A) filed by Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, on Feb. 27, for 'a mechanical joint architecture configured for automatic stress redistribution under fatigue loading.'
Inventor(s) include Dr. Shalya Raj; and Dr. Rohit Ravinder.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a purely mechanical fatigue-adaptive joint architecture configured to improve durability and reliability of structural connections subjected to cyclic or vibrational loading. The joint comprises a plurality of internal load paths, including a primary load path and one or more secondary load paths, in combination with elastic-plastic mechanical trigger elements. During initial operation, applied loads are transmitted predominantly through the primary load path. As service continues, localized fatigue accumulation or micro-plastic deformation develops within the primary load path or associated contact interfaces. When such deformation reaches a predefined mechanical threshold, the elastic-plastic trigger elements undergo controlled deformation, thereby causing an autonomous redistribution of load from the primary load path to one or more secondary load paths. This redistribution reduces stress concentration, suppresses fatigue crack initiation, and extends service life."
