Conclusion

  1. 1.

    The newly devised criteria and method of preliminary choice of structural steel make it possible to take into account, in addition to the properties of the material, also the dimensions and special traits of the structure, the existance of cracks, the conditions of loading.

  2. 2.

    We plotted experimental generalized dependences of the crack resistance (K* c/σu)2 on the reduced temperature under static and dynamic loading for low and medium-strength structural steels.

  3. 3.

    The newly devised method was experimentally substantiated, limitations were established for the applicability of the criteria contained in it and for the method as a whole connected with the thickness of the product and the structure of the steel.
