%X Material parameters are adjustable coeffcients in constitutive equations of the mechanical behaviour. Their identification requires a combined experimental and numerical approach, which results in a generally ill-posed inverse problem. Methods commonly applied in computational mechanics like optimisation and neural networks are addressed, and,problems like sensitivity, uniqueness and stability are discussed.
