Definition Of

Three different definitions of the yield point have been used in experimental work on the yield locus: proportional limit, proof strain and the ‘yield point’ by backward extrapolation. The theoretical implications of the ‘yield point’ by backward extrapolation are examined in an analysis of the loading and re-loading stress paths. It is shown, in connection with experimental results by Miastkowski and Szczepinski, that the proportional limit found by inspection is in fact a point located by backward extrapolation based on a small section of the stress-strain curve, near the elastic portion of the curve. The effect of different definitions of the yield point on the shape of the yield locus and some considerations for the choice between them are discussed.

Abstract: Protecting and promoting the health of workers in the mining industry is one of the most important problems of occupational pathology and health care. The structure and levels of prevention of occupational diseases are directly dependent on harmful and adverse factors of the production environment and labor process, adequately reflecting the state of production. Purpose: to study the issues of prevention of occupational and production-related diseases of mining and metallurgical plant workers. Research materials and methods: a dynamic observation of the health status of workers in the main industries of the mining and metallurgical plant (800 workers) was carried out. 92 patients with silicosis were examined. Results: Up to 92.8% of first-time occupational diseases are detected during periodic medical examinations. The prevailing sociomatic pathology is cardiovascular pathology, namely, arterial hypertension and diseases of the musculoskeletal system, mainly osteochondrosis of the spine. Prevalence of silicosis was observed in individuals with little professional experience (from 5 years old), young age and primary detection of patients in stage II silicosis, which was accompanied by respiratory failure. Conclusions: The prevention programme developed will ensure a high level of health care in terms of early diagnosis, rehabilitation and secondary prevention of both occupational and occupational diseases.
