Generalities on Constitutive Models
2023The balance equations of a body form an under-determined differential system, insufficient to yield specific results unless further relations are supplied. The balance equations for a continuum (free from internal structures) are the continuity equation, the equation of motion, and the balance of energy, namely five equations, for the fourteen unknowns

Instabilities and constitutive modelling
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006The plastics industry today sees huge wastage through product defects caused by unstable flows during the manufacturing process. In addition, many production lines are throughput-limited by a flow speed threshold above which the process becomes unstable. Therefore, it is critically important to understand the mechanisms behind these instabilities.

Numerical modelling of any problem requires noncontroversial statements of equilibrium and of kinematics or compatibility (the definition of strain); the constitutive response which links stress change and strain change is much more uncertain.

Constitutive modeling of bovine tendon
2017 21st National Biomedical Engineering Meeting (BIYOMUT), 2017In this study, tendons that holds skeletal and muscular system together are investigated with the help of hyperelastic material models and results of different material models are interpreted with the help of computer aided engineering programs. Axial forces are applied to bovine tendons in order to obtain stress-strain curve while doing constitutive ...
