- Abstract
- In the present study, the water impact loads on two-dimensional symmetric and asymmetric wedges were mainly studied. The impactpressure and force were measured during a vertical drop of the symmetric and asymmetric wedges. The measured pressure was compared with analyticsolutions. The measured force at a local area of the wedge was compared with the integrated pressures and analytic solutions. Some findings on symmetricand asymmetrical wedge drops are presented, and the reliability of the force sensor used for the measurement of the local impact force is discussed.
