YAN, Y, LIU, Y., PÁEZ CHÁVES, J., ZONTA, F. and YUSUPOV, A. 2018. Proof-of-concept prototype development of the self-propelled capsule system for pipeline inspection. Meccanica [online], 53(8), pages 1997-2012. Available from: https://doi.org/10.1007/s11012-017-0801-3

This paper studies the prototype development for the self-propelled capsule system which is driven by autogenous vibrations and impacts under external resistance forces. This project aims for proof-of-concept of its locomotion in pipeline environment...

Numerical and experimental studies of stick-slip oscillations in drill-strings. (2017)
Journal Article
LIU, Y., PÁEZ CHÁVEZ, J., DE SA, R. and WALKER, S. 2017. Numerical and experimental studies of stick-slip oscillations in drill-strings. Nonlinear dynamics [online], 90(4), pages 2959-2978. Available from: https://doi.org/10.1007/s11071-017-3855-9

The cyclic nature of the stick-slip phenomenon may cause catastrophic failures in drill-strings or at the very least could lead to the wear of expensive equipment. Therefore, it is important to study the drilling parameters which can lead to stick-sl... Read More about Numerical and experimental studies of stick-slip oscillations in drill-strings..
