Miniature Specimen Test System

Often, the component size puts limit on the fabrication of conventional specimens to study mechanical behaviour of materials. Efforts are therefore going on for quite sometime to evaluate the mechanical behaviour of materials using sub-sized or even or even miniature sized specimens. NML has recently procured a dynamic testing machine exclusively to study the mechanical behaviour of materials using small specimens. The system is capable of performing both static and dynamic testing of a variety of materials. Due to the high dynamic performance, the system can operate even at frequencies grater than 100Hz that makes the fatigue testing easy. Various types of testing that are possible with this system are tensile, high and low cycle fatigue, fracture toughness (KIC, JIC) and fatigue crack growth rate (FCGR) studies-all using really a small volume of material.The system is ideal for industries that cannot spare large volume of material that are typically required in destructive experiments and for those research organizations who are desirous to know the behaviour of materials across the length scale.
