A Review on Thermal and Structural Analysis of Disc Brakes in Motor Vehicles
Abstract: Braking is a technique that turns kinetic energy in a vehicle into mechanical energy that must be dissipated as heat. The frictional heat created at the disc-pad interface can cause high temperatures during the braking period. Thermal elastic instability (TEI), early wear, brake fluid vaporisation (BFV), and thermally stimulated vibrations can all be caused by frictional heat created on the rotor surface (TEV). In this research, a vehicle's solid type …

Digital Twin Assisted Intelligent Prediction of Polymer Composite Degradation Under Environmental Exposure
Abstract: Polymer matrix composites (PMCs) deployed in aerospace, marine, automotive, and renewable-energy structures are continuously subjected to coupled environmental stressors — ultraviolet (UV) radiation, moisture ingress, thermal cycling, and mechanical loading — that progressively degrade their mechanical performance. Conventional accelerated ageing tests and empirical lifetime models are time-consuming, destructive, and poorly suited to in-service, asset-specific degradation forecasting. This paper proposes a Digital Twin (DT) assisted intelligent prediction framework that fuses a …
