Experimental methods in Biomechanics

The principal aim of this line is the experimental study of the mechanical and microstructural behaviour of materials focusing on biomaterials and biological tissue. The analysis of the composition, morphology, microstructure and macroscopic behaviour allow to develop advance constitutive law able to reproduce the main physical features of the materials and afterward will be used in the rest of research lines of the group. The principal experimental tests and analysis are uniaxial, biaxial, compressive, shear stress, indentation, inflation, tomography, histology, in order to capture phenomena such as elastic, viscoelastic, fatigue or softening behaviours. Histological and microstructural tests permit to extract important information to model and simulate the response of the tissue at microstructural or cellular level.
