Influence of temperature on the identification of the elastic properties of composite materials

Standard test methods for the determination of elastic engineering constants like, among others, tensile tests, bending tests, torsion tests, require test specimens in which the stress and strain distribution are homogeneous. Standard test methods have proven their validity to the engineering society already a long time. However, when applied to complex materials like composite materials, some limitations of standard test methods become clear. To overcome these drawbacks, the department of Mechanics of Materials and Constructions of the Vrije Universiteit Brussel has developed a new material identification method called "the Resonalyser procedure"
