Density-Graded Cellular Aluminum
Conventional metallic foam processing seeks to maximize uniformity in pore size, relative density, and other aspects of foam structure in order to minimize property variation associated with the statistical nature of foams, and thereby increase their reliability in service. However, property uniformity is in many cases an inefficient approach to meeting overall design criteria, as demonstrated ...
متن کاملReliability-based design optimization for crashworthiness of vehicle side impact
With the advent of powerful computers, vehicle safety issues have recently been addressed using computational methods of vehicle crashworthiness, resulting in reductions in cost and time for new vehicle development. Vehicle design demands multidisciplinary optimization coupled with a computational crashworthiness analysis. However, simulation-based optimization generates deterministic optimum d...
متن کاملMultifunctional periodic cellular metals.
Periodic cellular metals with honeycomb and corrugated topologies are widely used for the cores of light weight sandwich panel structures. Honeycombs have closed cell pores and are well suited for thermal protection while also providing efficient load support. Corrugated core structures provide less efficient and highly anisotropic load support, but enable cross flow heat exchange opportunities...
متن کاملMetamodel Sensitivity to Sequential Adaptive Sampling in Crashworthiness Design
A study is conducted to determine the sensitivity of 2 topologically distinct metamodel types to variations in the experimental design brought about by sequential adaptive sampling strategies. The study focuses on examples encountered in crashworthiness design. Three sampling strategies are considered for updating the experimental designs, namely (i) a single stage approach, (ii) a sequential a...
متن کاملStudy on Optimal Design of Automotive Body Structure Crashworthiness
In this paper the optimal model of thin-walled sections of automotive body for structural crashworthiness is built. With computer design of experiment (DOE), the response surface model (RSM) of design can be obtained by carefully choosing a small quantity of samples in the design space. Pareto genetic algorithm (GA) is used in subsequently optimal design. With optimal design of thin-walled sect...
