Computability limits within the scope of computational mechanics

Abstract

The contribution deals with limits of computational mechanics as they unreel from those of physics, instrumental limits of computers and experimental instruments. It is shown that, more than on the above limits, our ability to predict the behavior of investigated phenomena depends on validity of models being employed. Author ponders about limits of applicability of continuum model as well as about limits of finite element approaches when applied to approximate solutions of fast transient tasks in solid continuum mechanics.
