STAND FOR RESEARCH deformation of the casing shells under local compression IN ZONE driving bands

摘要

The proposed utility model relates to the field of test engineering and can be used to test the strength of the projectile bodies. The technical effect is to determine the maximum range of the load starts deformation until the material discontinuity (cracks) in the local area leading to crimping girdle. The task is achieved by the fact that in the known device for investigating the strain body at the local crimping a zone leading girdle comprising press stand housing, the hollow punch, measuring the load and observation window, entered the hollow punch in the form of truncated circular pipes and lead gasket providing tightness .
