Question

length of Aluminum cylinder 100mm

load applied : 100N

diameter : 10mm

max force : 15.01KN

modulus ( Automatic young’s) : 8254.64MPa

The compression tests to be performed are focused on exhibiting the following types of instabilities in compression: Toble 1: L/D Ratio and Type of instability LD Ratio Type of Instability Buckling Shearing Double Barreling Barreling 5 or larger 25 LD5 2 < LD <2.5 Less than 2 with friction Less than 2 without friction Note that the friction in the first column amounts to the contact surfaces friction between the anvil and the top and bottom of the metal specimen. L/D ratio refers to the Length versus Diameter ratio of the specimen Buckling Part For the buckling of the solid circular metallic specimens [aininu perform the following Note down the load that causes out of plane deformation in the aluminum slender specimens. This can be done visually when the compression. Compute the critical buckling stress for the column using the following relation: o o n El where, Per is the Critical Load E is the Modulus of Elasticity L is the Length of the Column K is the Eflective Length Factor

12.71 Mpa is the least one. Hence it is the required critical buckling stress.
