The role and benefits of testing in product quality management

摘要

AbstractA key requirement for most engineered items is the ability to withstand the various loads that may be applied under conditions of use and of abuse that may reasonably be foreseen. To ensure that the strength requirement is satisfied, the designer must evaluate the levels of applied stress using appropriate calculation methods or by physical experiment. This paper considers the respective roles of computational and experimental methods of stress analysis, discussing the impact of changes in functional capability. Reference is made to the modern certification environment and the requirements of quality assurance, particularly related to the training of engineers and technicians in the necessary skills.The paper aims to present a balanced view of the role of experimental stress analysis, identifying areas where there are clear benefits. Some concluding comments are made regarding education, training and vocational qualifications.
