How Things Break: Thermal Effects (Webinar)

In How Things Break: Thermal Effects , you'll learn ...

• Types of failure associated with thermal effects
• Calculation techniques for estimating the influence of temperature
• How to design for variable and extreme service temperature

Overview

---

Since prehistoric times, humans understood that materials and systems change with temperature, and began to utilize that information for beneficial purposes. Annealing to restore ductility was known in 5000 BC. In 3200 BC, metal was melted to make castings in Mesopotamia. Differential hardening techniques for sword manufacture was developed in China and Japan near the beginning of the Common Era. Early steam engines are known from this time period as well.

Temperature can affect both materials and designs, sometimes in unforeseen ways. The Liberty Ship failures were a classic illustration of brittle fracture caused by low temperatures. Thermal conditions can cause a myriad of other problems, including thermal fatigue, creep, and increased corrosion rates.

This webinar presents how temperature can adversely affect materials and design, along with ways to mitigate these issues. Several case studies including the S.S. Schenectady, the Hasselt Bridge, and the Space Shuttel Challenger will be used to illustrate the concepts.
