Compression of New Generation Auxetic Sheets with Viscoelastic Material to be Used in Planing Hull Vessels

Abstract:

A new viscoelastic design known as auxetic sheet is proposed for the protection of GFRP planing hull vessels. The study of specimens made with auxetic sheets with different configurations in their geometry is presented to determine which one will be capable of absorbing the greatest amount of energy. For this, uniaxial compression tests were carried out using Hooke's 3D law on the designed specimens. The execution showed that the auxetic specimen in the "M" shape was the one capable of absorbing the greatest amount of energy from the applied force, obtaining the greatest capacity to absorb energy. The compression was considered quasistatic with the purpose of simulating an instantaneous slamming impact and being able to process the uniaxial test curve for the calculation of the elastic energy according to the level of damage in the specimen.
