Investigation Of An Energy Absorbing Device For Passenger Safety, Prakash Krishnaswamy
Investigation Of An Energy Absorbing Device For Passenger Safety, Prakash Krishnaswamy
Masters Theses
"Energy absorption by driving an oversized plunger through a longitudinally slit shell has been studied. The characteristics obtained by conducting several runs indicate that such a system could be used for energy absorption and for limiting the force required to drive the plunger through the shell. The characteristics can be readily altered by changing the dimensions of the tube. Details of the experimental set-up have been given.
Such an absorber has been adapted for mitigating injury sustained by the occupants in the interior of a colliding vehicle. Full advantage has been taken of the "Ride down" potential available to the …

Stability Of Filled Cylindrical Shell Columns, Yu Wen Tsao
Masters Theses
"This experimental investigation was conducted to study the stability of filled cylindrical shell columns. Two kinds of filler materials, flower clay (florist clay) and silica sand, were investigated. The cylindrical shells were made of 2024-T3 Reynolds aluminum tubing. Uniaxial compressive loading was applied directly to the filler materials through two loading rams, one at each end of the cylinder, (no loading was applied directly to the shell). Tests for investigating the load transmitting characteristics of the filler materials were performed, and the states of the stresses existing in the cylindrical shells were then obtained.
The buckling formula for thin-walled cylindrical …
