Analysis of Stress and Strain Leading to Musculo Skeletal Disorders of Work Related Activities Using Finite Element Method

K. V. Manjunath, Dr. B. Ravishankar

Abstract: Work-related musculoskeletal disorders (MSDs) are impairments of body structures such as muscles, joints, tendons, ligaments, nerves, bones or a localized blood circulation system caused or aggravated primarily by the performance of work and by the effects of the immediate environment where the work is carried out. Most work related MSDs are cumulative disorders, resulting from repeated exposures to high- or low-intensity loads over a long period of time. The symptoms may vary from discomfort and pain to decreased body function and invalidity. Although it is not clear to what extent MSDs are caused by work, their impact on working life is huge. MSDs can interfere with activities at work and can lead to reduced productivity, sickness absence and chronic occupational disability. The aim of work is to analyze the joints, using finite element method (FEM) approach with different case studies and to study on the role of ergonomics in preventing work related MSD disorders
