Ladislas Kubin passed away

It is with great sadness that we learned of the death of our colleague Ladislas Kubin, which occurred on October 18, 2022.

A graduate of the Ecole Centrale Paris in 1966, Ladislas Kubin carried out his thesis work at the Solid State Physics Laboratory of the University of Orsay. Recruited at the CNRS in 1968, he spent his entire research career there, first at the Electronic Optics Laboratory in Toulouse, then at the Physical Metallurgy Laboratory in Poitiers and finally at the Laboratory for Microstructural Investigations (LEM), a joint ONERA-CNRS research unit, which he joined from its creation in 1988 and where he continued his career until his emeritus in 2008.

Ladislas Kubin was an outstanding physicist and has profoundly marked the field of plasticity physics through experimental and theoretical research dealing with the individual and collective behavior of dislocations in order to better understand the deformation mechanisms of crystalline metals and alloys. On the experimental level, in the first part of his career, he endeavored to develop means of in situ study of the individual behavior of dislocations by transmission electron microscopy. This work then led him to develop precursor models for the prediction of dynamic aging phenomena in alloys such as the Portevin-Le Chatelier effect, then at the turn of the 1990s to initiate an original approach to mesoscopic simulation of the mechanisms of plastic deformation of metals. He was thus one of the founders of the French school of dislocation dynamics and one of the first to establish the link between their behavior and the plastic response of metallic materials.

Internationally recognized specialist, Ladislas Kubin was editor for the journal Acta Materialia and the author of the book “Dislocations, mesoscale simulations and plastic flow”. He received bronze and silver medals from the CNRS and the Gay-Lussac Humboldt prize.

Ladislas has trained many doctoral and post-doctoral students and interacted with many researchers in France and abroad. His knowledge in the areas of modeling and experiments was extensive and sought after.

A great physicist and valued colleague has passed away. His memory and his teaching remain.

His funeral will take place on Tuesday October 25, 2022 at 2:30 p.m. at the Saint Charles church in Biarritz (France).

Our thoughts go out to his family and loved ones to whom we extend our sincere condolences.
