Tensile properties of open-cell nickel foams
AbstractOpen-cell nickel foams with average pore size of 600μm have been subjected to room temperature tensile tests to explore their tensile properties. Using a state of the art extensometer of non-contact type, foam properties as ultimate tensile strength (UTS), yield strength (YS) and the Young’s modulus (E) have been measured accurately. An extensometer of non-contact type was applied for the first time to help the foam’s mechanical properties to be determined accurately. The reason behind the usage of this kind of extensometer is to avoid completely any minor deformation that might be caused by the attachment of conventional extensometer to the sample’s surface prior to testing. The function of this extensometer is based on the usage of a laser (CCD) camera that detects and records the dimensional changes as soon as the load is applied. The fracture behavior of foam cells was observed to be ductile. Complete separation of struts or cell walls took place successively by necking.
