Load Elongation MODELING: AN OVERVIEW

MODELING Representation of physically occuring phenomena using combination of experimental characterization, mathemtical equations and/or computational methods (NUMERICAL EXPERIMENT).

CONCEPT Load Elongation Complex system Load Simple Set-up

NUMERICAL EXPERIMENT Numerical Methods Equilibrium Compatibility Turbine blade Numerical Methods Load Elongation Equilibrium Compatibility

TYPES OF PROBLEMS Equilibrium problems Time-independent problems in solid mechanics or steady-state problems in thermo-fluid mechanics. Eigenvalue problems Steady-state problems whose solutions often requires the determination of natural frequencies and modes of vibration in solids and fluids. Problems involving the stability of structures and the stability of laminar flows. Propagation problems Time-dependent problems of continuum mechanics

Eigenvalue problem

EXAMPLE OF A MODEL Steady-state heat conduction through a thick wall
