Photoelastic stress of plastic glasses
Coloured light interference pattern of plastic glasses. When photographed through cross-polarised white light some transparent plastics display coloured interference effects, according to the pattern of residual stress within the plastic (a result of moulding manufacturing). Areas of similar colour represent regions under similar degrees of stress. This phenomenon, known as photoelasticity, is utilised in engineering situations. Plastic models of bridges, gears, axles, etc may be made and subjected to proportional loads in order to predict the stress patterns that might occur in the real objects

EDITORS COMMENTS
This print by Alfred Pasieka showcases the fascinating world of photoelastic stress in plastic glasses. Through the use of coloured light interference patterns, we are able to witness the intricate display of residual stress within these transparent plastics. The vibrant colours that emerge represent varying degrees of stress, providing valuable insights into the manufacturing process and potential weaknesses. Photoelasticity, as observed in this image, is a phenomenon widely utilized in engineering situations. By creating plastic models of bridges, gears, axles, and other objects susceptible to stress, engineers can subject them to proportional loads and predict the resulting stress patterns. This non-destructive testing method allows for a deeper understanding of how real objects may behave under different conditions. The beauty lies not only in the aesthetic appeal but also in its technological significance. These spectacles serve as a visual representation of scientific exploration at its finest – where light interacts with matter to reveal hidden stresses and strains that would otherwise remain invisible. Alfred Pasieka's skillful capture invites us into this realm where science meets artistry. It reminds us that even everyday objects like eyeglasses can hold secrets waiting to be uncovered through careful observation and analysis. Let this photograph ignite our curiosity about the unseen forces shaping our world while appreciating both their practical applications and sheer beauty they possess.
