Numerical and Experimental Investigation of Hollow Sphere Structures in Sandwich Panels

Review from Ringgold Inc., ProtoView:
Fiedler (engineering, U. of Avreiro, Portugal) focuses on different types of metallic hollow sphere structures (MHSSs), considering their morphology, topology, joining technology, material composition and mechanical properties. He begins by describing cellular metals, the potential for cellular lightweight structures, and sandwich structures, then proceeds to theoretical foundations in mechanics and heat transfer. He then concentrates on then methodologies, including the finite element method, his experimental methods and test procedures. Using various structures and the aforesaid finite element method, he evaluates several factors, analyzing impact behavior and thermal properties. His findings are interesting and well-supported by illustrations and references. However, he does not include an index. Nevertheless, the result serves as a professional reference and can also be used as a supplemental classroom text.
