The NSM group, formed by 3 researchers and 4 PhD students, is part of the Department of Continuum Mechanics and Structural Analysis at the University Carlos III of Madrid. Research lines include mechanical characterization at high strain rates, formulation of constitutive theories and analytical models for instabilities in ductile materials, nonlinear vibration in elastic structures, etc. The group has 5 on-going competitive grants, 2 National and 3 European, including an ERC Starting Grant.
