Metal Cutting Helps Researchers Understand Metals’ Behaviour Under Extreme Conditions

Researchers at Texas A&M University are taking a traditional manufacturing tool—metal cutting—and developing a more accessible method for understanding the behaviour of metals under extreme conditions.


In metal cutting, scientists feel knowledge of how materials deform and fail under harsh mechanical conditions is vital for studying and developing various technological applications, including manufacturing processes, crash testing of vehicles and impact testing for defence-related applications.

Because the cutting process involves locally shearing or deforming the metal to extreme levels under high rates, the team hypothesized that it could provide fundamental information on the material’s strength, resistance to plastic deformation or irreversible shape change.

“The research opens a new and interesting application for metal cutting as a ‘property test’ that material scientists and physicists can use to test their theories,” Dinakar Sagapuram, co-author of the paper that describes the new method, said in a media statement. “The number of mathematical theories of metal plasticity under high strain rates far outstrips the experimental data. So, the property information obtained using metal cutting can test which theories are valid and which are not.”

Observing Metal Movements

Sagapuram and colleagues used a high-speed camera to observe how metals deform and shear when they encounter a sharp cutting tool and use this information to deduce their basic property information. A significant challenge, however, lies in obtaining intrinsic material properties from the visual high-speed imaging data. 

“An important aspect of this research is to establish mathematical optimization techniques that guarantee global optimality, thereby achieving the best possible solution,” Hrayer Aprahamian, co-author of the study, said. “Otherwise, you might obtain solutions that seem satisfactory, but they don’t accurately describe the material.”

Metal cutting’s advantages over the testing methods used today are that it is simple and can produce a range of conditions that are difficult to achieve using conventional tests but are important from the standpoint of various engineering applications.

“We’re excited about the prospect of using cutting as a convenient method to determine material properties that are now obtained only with considerable difficulty,” Sagapuram said. “Because it is so simple, in principle, anyone with access to a machine shop can now obtain material data without sophisticated testing capabilities.”

Sagapuram noted the team recently started collaborating with the Los Alamos National Laboratory to cross-compare their data with more established material dynamic strength testing platforms available at the lab. These studies will contribute to validating the method and verifying whether different experiments on the same metal provide consistent data.

Aprahamian said their work to develop mathematical techniques also has potential applications outside material characterization.

“My group is extending some of these algorithms and techniques to the healthcare field, where we are using global optimization tools to construct robust screening strategies,” he said. “This can be used to prevent future outbreaks and improve screening for infectious diseases among the population.”
