IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

THREE DIMENSIONAL FRACTURE EFFECTS IN TESTS WITH CANTILEVER AND FIXED ENDS BEAMS
Author : Aleksey Marchenko , Evgeny Karulin , Peter Chistyakov , Devinder Sodhi , Marina Karulina and Alexander Sakharov
Results of in-situ tests with cantilever and fixed?end beams are discussed and analyzed. Numerical simulations demonstrated significant stress concentrations near the edges and close to the roots of simulated beam. Maximal tensile stresses in the beam could be responsible for the initiation of the root crack. These values of stresses are used for the calculation of critical wave amplitudes when floating ice sheet is failed. Failure scenarios of beams with fixed ends observed in in-situ tests are analyzed in the plane of principal stresses, and the stresses are compared with the failure envelope using numerical simulations.
