Abstract: First-order hyperbolic partial differential equations with two internal variables have been used to model biological and epidemiological problems with two physiological structures, such as chronological age and infection age in epidemic models, age and another… read more here.

Abstract: The µ damage model provides good results under bi-axial compression loads and enables stiffness recovery due to crack closing under cyclic loading. However, this model suffers from numerical damage localization and is unable to preserve… read more here.
