What is the thermal expansion equation for fasteners?
The temperature necessary to create the axial stress or force, Ft , (when the stress is below the elastic limit) can be found with the following equation: T – T o = change of temperature realized by fastener.
When is restricted expansion converted to axial force?
When restricted expansion is “converted” to stress – then (1), (2) and (3) can be combined to The axial force acted by the restricted bar due to change in temperature can be expressed as A DN150 Std. (6 in) steel pipe with length 50 m (1969 in) is heated from 20oC (68oF) to 90oC (194oF).
What is the formula for thermal expansion, stress and strain?
Answer Wiki. Thermal expansion occurs when an object expands and becomes larger due to a change in the object’s temperature. This equation describes a linear thermal expansion : The thermal strain or deformation for an unrestricted thermal expansion can be defined as the ratio of change in length to the original length.
How is the thermal expansion of an object expressed?
When an object is heated or cooled, its length changes by an amount proportional to the original length and the change in temperature. The linear thermal expansion – the change in length – of an object can be expressed as dl = L0 α (t1 – t0) (1)
