Developing better materials for everyday life

TheÌýincreasedÌýdemand for specialised products and technologies is driving manufacturing innovation and the development of newÌýadvancedÌýmaterials.ÌýMany objects in our everyday life have been transformed—and in most cases—improved by the application ofÌýadvanced materialsÌýlike metals, ceramics, gels, polymersÌýandÌýcomposites.ÌýThe benefits come not only from greater quantities of existing materials at reducedÌýcostsÌýbut also from the development of materials with totally new properties that enhanceÌý²õafety and sustainability. These new materialsÌýoutperform conventional onesÌýas they haveÌýproperties thatÌýimproveÌýtoughness andÌýdurability. ÌýÌý

ToÌýensure that the engineering structures made of these materials can perform as required,Ìýthey need to be tested underÌýdynamic loadingÌýconditionsÌýto see howÌýtheyÌýbehave. Whether it’s a mobile phone dropping onto a hard surface, a car crashing into a brick wall, a bullet striking an armour plate, or even a meteorite crashing to Earth, impact dynamicsÌýinvestigates collisionsÌýand how materials and structures perform and function when subjected to a range of extreme loading conditions.

Impact

Using a synergy of our expertise regarding advanced materialsÌýand of their behaviour under dynamicÌýimpact loadingÌýconditions weÌýfocus onÌýdeveloping resilient materials and structures for engineering applications. UsingÌýexperimentalÌýinvestigation, weÌýtest materials over a wide spectrum ofÌý²õtrain ratesÌýranging fromÌý10-3Ìýto 107Ìý²õ-1.ÌýÌý
