... strength. The wear tests have shown that high fly ash content can improve wear resistance. The analysis of the fracture and wear surfaces showed that the particles are distributed efficiently. Finally, this composite is intended for use in new buildings as the building block of the future, the design...

... pendulum impact tester at SCK•CEN demonstrated that the static and dynamic performance of instrumented strikers is influenced by their design, especially the location of the strain gauges. To further improve our design know-how, instrumented ASTM (8 mm radius) and ISO (2 mm radius) strikers are developed...

...Anton TenWolde Many of our current recommendations for moisture and condensation control are not based on quantitative analysis under a consistent set of design assumptions, even though a growing number of computer tools are beginning to make such analysis practical. To address this issue...

...M Atkinson Development of a compact, versatile yet accurate extensometer is described. The extensometer has a lever mechanism with added linkage to maintain the transducer alignment exactly parallel to the gage length. The design features linear translation through a large working range, variable...

... a means of evaluating the potential for lateral collapse of a wood pallet design. A minimum horizontal force required to cause overturning of stringers is calculated from input data on pallet size and shape, unit load weight, and the moment-resistance characteristics of the joints. A relative measure...

... and the rigidity of the nailed joints. This report gives design formulas for calculating the short-term constant environmental condition bending stiffness and bending strength of three-stringer pallets used in racks. The formulas treat an arbitrary rigidity of the nailed joints and an arbitrary area of the top...

...WL Ducker; CVG Vallabhan; WS McMullin A critical evaluation of the mechanical design of beam testing apparatus used to determine the flexural strength of concrete by ASTM methods C 78-64(1972) and C 293-68 is presented. Two approaches were used in the evaluation: (1) an experimental deformation...

...HF Hardrath The paper reviews briefly the current design philosophies for achieving long, efficient, and reliable service in aircraft structures. The strengths and weaknesses of these design philosophies and their demonstrated records of success are discussed. The state of the art has not been...
