Research on dynamic creep strain and settlement prediction under the subway vibration loading
This research aims to explore the dynamic characteristics and settlement prediction of soft soil. Accordingly, the dynamic shear modulus formula considering the vibration frequency was utilized and the dynamic triaxial test conducted to verify the validity of the formula. Subsequently, the formula was applied to the dynamic creep strain function, with the factors influencing the improved dynami...

Predicting the settlement of coarse granular materials under vertical loading
Granular materials are widely used in industrial processes despite their complex and poorly understood mechanical behaviour both in static and dynamic regimes. A prototypical example is the settlement and compaction of a granular bed under vibrational loading. The elementary mechanisms of this process are still unclear and there is presently no established theory or methodology to predict the s...
متن کاملPrognostics implementation of electronics under vibration loading
In this paper, a methodology is developed for monitoring, recording, and analyzing the life-cycle vibration loads for remaining-life prognostics of electronics. The responses of printed circuit boards to vibration loading in terms of bending curvature are monitored using strain gauges. An analytical model calibrated by finite element analysis is developed to calculate the strain at interconnect...
متن کاملCreep Prediction Using The Non-Linear Strain Energy Equivalence Theory
The Non-Linear Strain Energy Equivalence Theory, a semi-empirical model, is utilized to predict longterm creep from short-term compressive stress-strain experiments conducted at different strain rates. Stress-strain experiments in uni-axial compression are performed at strain rates of 3 and 0.03 %/minute to predict creep behavior and stress-strain data at several strain rates for an immiscible ...
