In the Lilliputian world of nanofabrication, where billions of microscopic circuit elements are sculpted or imprinted on a fingernail-sized silicon chip
We develop methods to evaluate the mechanical behavior of micro- and mesoscale metal alloys to fracture, and Micro Electro Mechanical Systems (MEMS) materials
All inorganic materials contain point defects in the form of impurities, interstitials, or vacancies. Common imaging techniques fail to capture these defects
Polymers play a central role in high rate impact mitigation applications ranging from helmets, to body armor, to aircraft and spacecraft protective coatings. A
Critical parts for defense, aerospace, and medical applications must be formally qualified prior to use. Currently, extensive empirical testing consisting of

Simultaneous rheology and conversion measurements of neat and composite epoxy resins reveal that conventional models neither accurately nor fully describe the
This paper critically examines existing ductile crack growth (DCG) corrections for J integral values calculated with the multi-specimen and elastic compliance

High cycle fatigue life of laser-powder bed fusion (L-PBF) parts depends on several factors; as-built surfaces, when present, are a particular concern. This
This in-situ indentation system can be integrated into electron microscopes as well as being run in other unusual setups. With a load capacity of 150 mN, this
The TA Instruments RPA elite rubber process analyzer (RPA) is a strain-controlled rotational shear rheometer for the characterization of polymers, composites
The Security Technologies Group has a 4-m-tall drop tower that can be configured for a wide variety of impact and impact-related testing. This drop tower is
