    Liu, Yang; Paez Chavez, Joseph; De Sa, Rulston; Walker, Scott (Springer https://doi.org/10.1007/s11071-017-3855-9, 2017-10-31)
    LIU, Y., PAEZ CHAVEZ, 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 ...
  • Path-following analysis of the dynamical response of a piecewise-linear capsule system. 

    Paez Chavez, Joseph; Liu, Yang; Pavlovskaia, Ekaterina; Wiercigroch, Marian (Elsevier https://doi.org/10.1016/j.cnsns.2016.01.009, 2016-08)
    PAEZ CHAVEZ, J., LIU, Y., PAVLOVSKAIA, E. and WIERCIGROCH, M. 2016. Path-following analysis of the dynamical response of a piecewise-linear capsule system. Communications in nonlinear science and numerical simulation [online], 37, pages 102–114. Available from: https://doi.org/10.1016/j.cnsns.2016.01.009
    The dynamical response of a piecewise-linear capsule system is studied by means of path-following techniques in this paper. As the capsule model belongs to the class of piecewise-smooth dynamical systems involving impact ...
