Caracterización experimental del efecto de la tasa de deformación en el comportamiento mecánico de un compuesto termoplástico
Publicado 2017“…A key factor for the application of these materials is their strength at high strain rate due to the structures are subjected to dynamic loads such as impact with foreign bodies, projectile impacts and shock waves, and the mechanical properties are significantly affected for these loading conditions [3]. This means that reliable design of the composite components requires the detailed characteristics of the materials at high strain rates, however because of the unavailability of dynamic properties, static properties are used in material selection and design, which can produce excessive design weight or cause unexplained and untimely failure [4], [5]. …”
