Failure Analysis Of Plastic Products Through Stress Analysis Method Seminar

Plastics products frequently fail or crack unexpectedly. Many failures occur when applied stresses are below the tensile strength of the material, while others result from over load or excessive stress. It is, therefore, important to understand the role of applied stresses in a specific failure through stress analysis, which often provides a clear direction to failure analysis.

The stress analysis procedures range from very simple strength of materials calculations to highly sophisticated Finite Element Analysis (FEA) and experimental methods. The effectiveness of the stress analysis can be greatly improved through training in selection of methodology, and meaningful interpretation of results. An overview of theoretical stress analysis methods including model selection, application of boundary conditions, stress-strain models, and yield criteria for plastic materials will be presented.

A brief overview of experimental stress analysis methods for plastics by strain gauges, photo-elasticity and brittle coatings will be presented. A number of case histories of plastics failure analysis will be presented throughout the course to highlight the power and limitation of stress analysis methods. Stress analyses with varying degrees of sophistication played an important role in determining the cause of failure in each case.

The seminar attendees will learn many practical approaches to the use of stress analysis in failure investigations of plastics products.
