In the second half of April, a colloquium focused on the Fatigue mechanism was held at the Institute of Physics of Materials, Czech Academy of Sciences. The results of our institute's research were presented by a colleague, Ing. Roman Štěpánek, Ph.D., within the presentation entitled: The influence of loading mode on fatigue properties of AZ91 alloy processed by SPH method (Štepánek R., Pantělejev L., Fintová S., Guagliano M., Kunz L.)
