MSc Rafael Arturo Rubio Ruiz developed a numerical strategy to calibrate fatigue models using multiple types of experimental data, extending the predictive capabilities of existing models to realistic loading conditions, which include multiaxial loading and non-homogeneous stresses.
In his research, Rubio Ruiz developed a mesoscale finite element model of granite, calibrated using multiple types of experimental data in one systematic approach. He used this rock model to investigate how alternating current (AC) excitations can facilitate rock breakage.
"This research contributes to both the prevention of unforeseen material failure in critical applications across industries and the optimisation of rock breakage processes in mining applications", says Rubio Ruiz.
Rubio Ruiz is currently working as Expert, Structural analysis at Wärtsilä, a global leader in complete lifecycle solutions for the marine and energy markets, where he continues using numerical strategies to analyse material integrity under different types of cyclic loading conditions.
