About

      My latest  works were focussed on the  development of the analytical solutions for the through-wall temperature response and thermal stress components in a hollow cylinder due to thermal transient in generals, and particularly for the sinusoidal transient thermal loading case.
      In a second stage, based on these stress distributions solutions,  a methodology for assessment of thermal fatigue crack growth life has been developed.
    At the moment I'm working on the methodology based on the stochastic modeling of thermal fatigue crack growth, that can be used to analyze and improve the screening criteria proposed to avoid cracking issues in nuclear piping, especially in tee connection where turbulent mixing of flows with different temperature can occur.
    To date, I am interested also in various applications of the EAM (engineering assessment methods). Currently, I work on the deterministic and probabilistic approaches of leak-before-break in nuclear piping, using the probabilistic fracture mechanics principles and the MATLAB environment.
