WebMar 2, 2016 · Dynamic buckling of an elastic column under compression at constant speed is investigated assuming the first buckling mode. Two cases are considered: (1) an imperfect naturally curved column (Hoff’s statement) and (2) a perfect column with an initial lateral deflection. The range of parameters where the maximum load supported by a … WebAxia packed preparative columns involve a single axial compression step, unlike conventional packed preparative columns. The ideal column bed density is custom calculated and automated for each specific media and column size. Computer control of the entire process ensures both proper bed density and column uniformity every time.
