Metoda elementów czasoprzestrzennych w zagadnieniach geometrycznie nieliniowych

The paper contains a method of solution of dynamically and geometrically non-linear problems by the use of the space – time element method (STEM). The stress-strain relation (the 2-nd Piola-Ktrchhoff tensor – the Green tensor) has been defined in different form. It has been proved that the method of formulation of the constitutive relations plays a significant role in the case of large strains. This effect has been demonstrated on examples.
