Hydroelastic analysis of axially loaded Timoshenko beams with intermediate end fixities under hydrodynamic slamming loads

Hydroelastic DLF (Dynamic Loading Factor) of undamped Timoshenko beam (length L) to a hydrodynamic impact-induced slamming load of vertical impact velocity V, with end-fixity torsional spring constant log10Kθ=−6,0,1,2,6;Kθ=kθLEI; deadrise angle β=10°, slenderness ratio hL=0.02, no axial load. Non-D loading period or wetting time τ=2LsinβVπωn12π,ωn1 is the fundamental frewuency of the Timoshenko beam (rad/s).
