Professor of Solid Mechanics Dr Jukka Tuhkuri, from Aalto University’s Department of Mechanical Engineering, joins Professor Lucy Blue to uncover the real story behind Ernest Shackleton’s legendary ship, Endurance. While on board the Endurance22 Expedition vessel searching for the wreck, Dr Tuhkuri was collecting ice cores for his own research when he became intrigued by the theories around the crushing of the ship by ice.  Studying the original ship’s plans, archival material, and applying his cutting-edge ice mechanics research, Dr Tuhkuri reveals surprising new insights into the ship’s design weaknesses, flaws Shackleton himself recognised, yet believed were worth the risk. The discussion explores how the ship’s structure, the ice conditions in the Weddell Sea, and the loss of the rudder combined to seal its fate on 21 November 1915.
