Strength of Materials Aims and scope

Conclusions

  1. 1.

    It is suggested to represent the characteristic of vibration strength of materials with a view to the dissipation of vibration energy on inelastic deformation in the form of the dependence of the maximal specified initial stress on the number of units of loading by free damped oscillations to destruction of the specimens.

  2. 2.

    A method was worked out and a stand devised for investigating the vibration strength of steels.

  3. 3.

    Steels used in parts of percussive equipment were investigated. It was shown that, regardless of their good damping properties, specimens of steel ITs-1A have the lowest endurance.
