Abstract
Aluminum square tube with a geometrical initial imperfection, i.e. a small distortion or hole on the tube wall before deformation is prepared in dynamic deformation test. Location and shape of the buckling deformation of the tube depend on the size and location of initial imperfection. Experimental results agree approximately with those of the finite element method analysis.
