Inverse problems can be found in many topics of engineering mechanics. There are

many successful applications in the fields of inverse problems (non-destructive

testing and characterization of material properties by ultrasonic or X-ray

techniques, thermography, etc.). Generally speaking, the inverse problems are

concerned with the determination of the input and the characteristics of a

mechanical system from some of the output from the system. Mathematically, such

problems are ill-posed and have to be overcome through development of new

computational schemes, regularization techniques, objective functionals, and

experimental procedures.
