Abstract [en]

The vibration characteristics of a cohesively cracked Euler-Bernoulli beam are investigated using the modified line-spring method. The crack plane is statically loaded in bending into the nonlinear region and small amplitude vibrations are superposed about this state. The deflection solution form is then separated into the zeroth order linear and first order nonlinear components. Several vibration characteristics such as deflection, slope and modal amplitude are studied as a function of the applied static moment.
