摘要：In this study, investigation the temperature distribution of vibration beam under force harmonic load
applied with force frequency equal to (0.9 from beam natural frequency). Where, the investigation included
study the effect of crack depth and position on the temperature distribution in the beam. There, the beam
investigating made of carbon steel materials and supported with various boundary condition. In addition,
the investigation included using experimental and numerical technique to calculate the temperature of
beam with crack and uncrack effect, with various depth and position crack influence. Therefore, the
experimental technique included building of rig vibration and applying to harmonic load on the beam,
supported with various boundary condition, and then, measurement the temperature in the beam by using
thermal camera. Also, the numerical technique included calculated same variable evaluated by
experimental technique with same parameters effect, by using finite element method with using of
COMSOL program, and then, calculate the change in the temperatures that appeared in the numerical
solution and compare them with the change in the calculated temperatures in experimental work.
Therefore, the comparison of results shown that the experimental and numerical results are agreement with
maximum error about (10.8%). Where, the results shown that the temperature change with crack beam
more than the temperature change of beam without crack, for various beam boundary conditions supported.
In addition, the results shown that the time required to stability the change of temperature, due to applied
harmonic load, increase for beam with crack effect.
