Studi Experiment Uji Buckling Dengan Variasi Tumpuan Dan Material Benda Uji

Abstract

Most structures that have slender or thin dimensions and are subjected to stresses, experience buckling or buckling stability problems. Buckling is a process in which a structure is unable to maintain the indicated shape, the shape changes in order to find a new balance. In this study, the test equipment used was a simple buckling test with a maximum load of 500 N, using brass and aluminum test materials with dimensions of 24 cm long and 3 mm in diameter. In this study aims to obtain the value of the theoretical and actual critical load caused by the test object at various supports. In this study, the author is able to calculate the theoretical critical load and the actual critical load of the various supports, namely clasps, hinges, and hinges. From the results of the research that has been carried out, the theoretical critical load values are 79.25N on hinge supports, 158.51N on clamp hinge supports, and 317.02N on brass clamp supports. While the aluminum material is 61.64N on the hinges pedestal, 123.28N on the pin hinges, and 246.57N on the pin pedestals. Then the average value of the actual critical load obtained from the brass material is 83N at the hinge support, 134N at the clamp hinge support, and 226.5N at the clamp support. While the aluminum material is 71.5N on the hinges, 106.5N on the pins, and 181.5N on the pins.
