Assessing Failure Risk of Existing Metro Stations During Unilateral Large-Scale Excavation: An Experimental and FE Perspective
Introduction Urban rail systems are lifelines in modern cities, yet their safety can be challenged when nearby large-scale excavations unfold. This article synthesizes experimental insights and finite element (FE) analyses to understand the failure risk of existing metro stations during unilateral, large-scale excavation. Drawing on established research in soil-structure interaction and case studies from major…

Failure Risk of Metro Stations During Unilateral Large-Scale Excavation: A Geotechnical Perspective
Introduction The stability of existing metro stations under nearby construction is a critical concern for urban infrastructure. When unilateral large-scale excavation occurs adjacent to underground transit facilities, the surrounding soil-structure system experiences complex stress changes that can elevate the risk of station or tunnel failure. This article synthesizes findings from experimental studies and finite element…

Experimental Insights into the Failure Risk of Existing Metro Stations Under Unilateral Large-Scale Excavation
Introduction Urban metros are vital arteries of modern cities, but their long-term performance can be challenged by large-scale ground works nearby. A growing body of research examines how unilateral excavation—where the soil is removed on one side of an underground structure—affects the stability and serviceability of adjacent metro stations. This article synthesizes experimental findings and…

Fatigue Life Prediction of Vehicle Rubber Elastic Support Components Based on Physics
Introduction Rubber elastic support components are vital in automotive vibration isolation, absorbing road irregularities and reducing transmitted forces to the chassis and occupants. These non-metallic materials exhibit complex behavior under long-term cyclic loading, where temperature, frequency, and load amplitude influence fatigue life. A physics-based fatigue life prediction framework offers a systematic way to quantify reliability,…

Fatigue Life Prediction for Vehicle Rubber Elastic Supports Using Physics
Introduction Rubber components play a crucial role in automotive vibration isolation, acting as non-metallic elements that decouple road excitations from the vehicle structure. Among these, rubber elastic supports (such as engine mounts and suspension bushings) endure long-term cyclic loading that leads to fatigue damage. A physics-based approach to predicting fatigue life seeks to connect material…

Fatigue Life Prediction of Vehicle Rubber Elastic Supports: A Physics-Based Approach
Introduction Rubber components play a pivotal role in automotive vibration isolation, absorbing shocks and dampening noise while maintaining ride comfort. Among these, rubber elastic supports (often called mountings or bushings) are exposed to prolonged cyclic loading, temperature variation, and environmental aging. Predicting their fatigue life is essential for reliability, maintenance planning, and safety. A physics-based…
