Waloddi Weibull

from Wikipedia, the free encyclopedia

Ernst Hjalmar Waloddi Weibull (born June 18, 1887 in Vittskövle , † October 12, 1979 in Annecy ) was a Swedish engineer and mathematician.

Weibull came from a family who immigrated to Sweden from Schleswig-Holstein in the 18th century . In 1904 he joined the Swedish Coast Guard as a midshipman, where he worked his way up to major. During his years of service, Weibull attended the Royal Technical University of Stockholm , which he graduated in 1924. Weibull later earned a PhD from Uppsala University .

During several expeditions on the research vessel Albatross in 1914 in the Mediterranean, the Caribbean and the Pacific Ocean, Weibull wrote a first publication on the propagation of blast waves and developed a method for studying the thickness of sediments and the nature of the seabed using explosion sources . The sea seismic method is still used today in oil exploration .

In 1941, Weibull received a professorship in technical physics at the Royal Stockholm University of Technology . He wrote various papers and publications, e.g. B. in the areas of material strength, fatigue or fracture behavior of solids . His best-known research is concerned with the Weibull distribution named after him , which has proven to be very useful in connection with issues such as material fatigue in brittle bodies, the failure of electronic components or in statistical studies of wind speeds.
