Shear Testing Essentials
Shear testing produces shear property data for material specifications, research and development, quality assurance, and structural design and analysis. Shear properties can be calculated via different test types including tension, flexion, and compression as well as different test set ups such as the lap shear method, V-notched rail method, short beam method, and more.

Sheet Metal Tension Testing
Sheet metal forming operations consist of simple bending, to stretching to deep drawing of complex parts. The mechanical properties of the sheet material greatly influence its formability, which is a measure of the amount of deformation the material can withstand prior to fracture. This blog post covers important definitions determining sheet metal characteristics, the test methods, and the equipment used to quantify them.
Nanoindentation processes in full view
The microelectronics revolution is one of the most influential drivers of current industrial developments. To probe the mechanical properties of ever shrinking materials and components, nanoindentation has come to be an omnipresent and indispensable method. In a recent combined experimental and computational approach, an international team of scientists was for the first time able to resolve the dynamic atomistic processes taking place at the elastic-plastic transition during nanoindentation.

Environmentally induced exceptional points in elastodynamics
We study the nature of an environment-induced exceptional point in a non-Hermitian pair of coupled mechanical oscillators. The mechanical oscillators are a pair of pillars carved out of a single isotropic elastodynamic medium made of aluminum and consist of carefully controlled differential losses. The interoscillator coupling originates exclusively from background modes associated with the “environment,” that portion of the structure which, if perfectly rigid, would support the oscillators without coupling.
Independent control of dynamic material properties by exploiting structural hierarchy and intrinsic structural gradients
Achieving high damping and stiffness is challenging in common materials because of their inter-dependent scaling. Controlling extreme mechanical waves requires synergistically enhanced damping and stiffness. We demonstrate superior damping and stiffness in vertically aligned carbon nanotube (VACNT) foams that are also independently controllable by exploiting their synthesis-tailored structural hierarchy and structural gradients. They exhibit frequency- and amplitude-dependent responses with dramatically tunable dynamic stiffness while maintaining constant damping.
