In both residential and commercial buildings, heating and cooling cycles can take a toll on piping systems. When pipes expand due to heat and contract when they cool, they stress joints, supports, and ...

When temperatures increase, most materials tend to expand, causing a change in material dimensions. When two materials that exhibit different thermal expansion behaviors are in direct contact, such as ...

The Eiffel Tower, for example, is about 10 to 15 centimeters taller in summer than in winter due to its thermal expansion. However, this effect is extremely undesirable for many technical applications ...

When consideration is given to track engineering and maintenance, many newcomers to the railroad industry don’t realize what massive amount of effort is put forward to properly manage thermal rail ...

(Structural analyses top the list.) And although most thermal simulations are done with finite elements, there are advantages to methods that work with networks of thermal bodies connected by links ...

A group of researchers led by Helmholtz-Zentrum Berlin (HZB) in Germany and China’s Henan University investigated repeated thermal stress cycles, reflecting diurnal cycles, on the degradation of metal ...

Thermal management deals with problems arising from heat dissipation, thermal stresses and warping. It is critical in the packaging of power semiconductors and other microelectronic and optoelectronic ...

Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration has ...

Thermal-induced stress is now one of the leading causes of transistor failures, and it is becoming a top focus for chipmakers as more and different kinds of chips and materials are packaged together ...

In the experiment, perovskite solar cells were repeatedly cooled to minus 150 degrees Celsius and then heated to plus 150 degrees Celsius. The changes in the microstructure of the perovskite layer and ...
