Ritiri e deformazioni dei materiali plastici

Shrinkage and Deformation of Plastic Materials We explore finite element analysis, focusing on the challenges related to material shrinkage and deformation. 👇Discover our technical support services👇 https://www.lati.com/it/about-lati/as... All materials undergo dimensional changes in response to temperature changes. In the past, material shrinkage was not a concern, but as engineering needs evolved, accurate measurement of thermal expansion has become crucial, especially for joining plastic and metal parts. Manufacturers began providing material shrinkage information in their technical data sheets, initially using proprietary criteria and later adopting standardized criteria from organizations such as STM and ISO. Concrete examples of different shrinkage factors, focusing on simple shapes to highlight the complexity of the variables involved. Factors such as length-to-diameter ratio, fiber orientation, cooling conditions, and mold design can significantly impact material shrinkage. 👇Discover our technical assistance services👇 https://www.lati.com/it/about-lati/as... 🔔Subscribe to our channel!
