ABSTRACT:
Apparatus for limiting the buckling of an elongate test specimen during a compression test comprises a stabilizer through which the specimen 6 passes when assembled into a testing machine, the stabilizer having a body 1, 4 which is arranged to hold stiff stabilizing rods 2, 3 adjacent to those opposite faces of the specimen liable to buckle. The rods 2, 3 are adjustable to accommodate specimens 6 of different thicknesses. The stabilizer slidably engages the specimen grips 11 of the testing machine and is supported thereby so that premature shear failure of the specimen adjacent to the grips is also prevented.
