Document Summary

Eng 4t04/6t04 materials selection in design and manufacturing. Date: monday november 5, 2012, 09:30 10:00. A sandwich panel conforming to the geometry shown in figure 1 is to be manufactured from a polystyrene foam and an aa6061-t6 alloy sheet having the properties and standard stock thicknesses listed in table i. The panel is to be used in an application where the ambient temperatures (ti) and heat transfer coefficients (hi) are defined per figure 2. The maximum steady-state heat flux through the panel ( )max is specified to be 65 w/m2 and the minimum sandwich panel flexural modulus ( flexe is specified to be 7 gpa. Using the materials and stock thicknesses specified in table i only, design a suitable sandwich panel to meet both design constraints. Assume ks = 1 and that the system is under steady-state heat transfer conditions. Useful equations can be found on the next page. q .
