Professor Wei Sha from Queen's School of Planning, Architecture and Civil Engineering has been testing how safe vehicles with titanium alloys are when attacked by bullets or explosions.

Professor Sha's research examines the damage tolerance of the popular material titanium. It is the first research of its kind to reveal the reasons behind the deformation and damage of titanium alloys under strong impact or fast applied force.

Military based in Afghanistan currently use land rovers which have titanium alloys.

Professor Sha has already discovered that like virtually all metals, titanium is weakened under force and at an elevated temperature.

He said: "This research started with a study visit by Professor Guoqing Wu, from Beijing University of Aeronautics and Astronautics, a university specialised in aerospace education and research. The success of the research shows the importance of developing international collaboration."

Professor Sha is aiming to go a step further with the research and predict what will happen if the alloys are compressed.

This compression process normally happens when manufacturers want to transform the material into a plate or short drum shape by using a compression machine. This form of titanium is often used in the aeronautic and astronautic industry.

But compression can also happen when faced with an unexpected situation such as when the military are being attacked by bullets or explosives.

Although the process usually happens at room temperature, the temperature inside the alloy could heat up to several hundred degrees as heat is generated through deformation. Professor Sha predicts this could weaken the alloys and endanger the lives of those travelling in the vehicle.

He said: "Sometimes, deformation of a metal is a desirable property. It is essential for completing its forming and shaping process. In other occasions, deformation is unwanted, especially in a finished product, which people want to maintain its shape during service. Either way, it is important to understand the deformation behaviour, so as to be able to devise methods to control the deformation."

He set out to make sense of the complicated phenomenon so that if an explosion or military attack occurs those involved will know what to expect.

The end research could be used by manufacturers for advice on safety, material selection, optimisation and component design.

Professor Sha hopes that this new model will cut back on the number of costly experiments which are needed to test the safety of titanium.
