What is the rail temperature stress?
Temperature stress: as a result of changes in temperature, the structure or member produces an extension or contraction, and when the expansion is limited, stress is generated within the structure or member, known as thermal stress
Thermal stress is also called thermal stress". Stress due to the temperature rise and fall of a body or the temperature of each part of an object. For example, the workpiece is welded by the stress caused by local heating; there is a gap between the rails of the rails to avoid or reduce the possible temperature stress.
The rail temperature stress is that the rail will expand and contract when the temperature changes. It is bound by the fastener and the internal force.
