Experimental Facilities
Hypervelocity Impact Facility (planned completion 2018) This facility will be a state-of-the-art hypervelocity launcher and diagnostics to probe the behavior of materials in extreme environments with applications in planetary formation and shielding design. High-speed imaging and other diagnostics will provide insight into behavior at impact velocities above 5 km/s. LEARN MORE
Laser Shock Facility This facility will use a high-powered laser to ablate a surface layer of the target material, generating shock waves at high shock pressures. State-of-art diagnostics allow measurements to be made to understand material response at these pressures at bench-top size scales. LEARN MORE
Plate Impact Facility The plate impact facility is comprised of a gas gun and target chamber and interferometer laser diagnostics. Normal plate impact and pressure-shear plate impact experiments at velocities up to 200 m/s and strain rates up to 106 1/s can be achieved. LEARN MORE
Kolsky Bar Facility The Kolsky bar facility tests materials in uniaxial or biaxial confined stress states at strain rates of 102 to 104 1/s over a range of temperatures. Equipment includes a conventional Kolsky Bar, a Desktop Compression Bar, and a multiaxial bar for tension and torsion. High-speed imaging allows in-situ visualization during testing. LEARN MORE.
3D Characterization Facility This facility contains a field emission SEM with EBSD and EDS detectors and an in-situ nanoindenter stage. Serial sectioning and imaging are being developed, making use of in-situ surface milling from a femtosecond laser. The femtosecond laser can also be used for micromachining. LEARN MORE
Specimen Preparation Facility This facility contains several pieces of equipment to prepare specimens for both testing and characterization. Equipment includes low and high speed saws, automated polishing machines, a lapping machine, an electro-polisher and an ion-milling machine. LEARN MORE
Shock Tube Test Facility This facility uses a 3-inch shock tube to dynamically load soft materials and tissue specimens. Dynamic pressure measurement and high-speed 3D digital image correlation capture material response. This facility is Biosafety level 2 and includes a biosafety cabinet for preparation of tissue samples. LEARN MORE
Drop Weight Test Facility  The high energy drop tower delivers impacts between 1 and 30 m/s with specified energy up to 1800 Joules to both solid materials and tissue specimens. An environmental chamber allows control of ambient temperature, and tests can be visualized with high-speed imaging. LEARN MORE

 

Computational Facilities
Maryland Advanced Research Computing Cluster (MARCC) The Maryland Advanced Research Computing Cluster (MARCC) is shared by Hopkins and the University of Maryland. MARCC has about 20,000 cores  and a combined theoretical performance of over 930 TFLOPs. It also features two types of storage – standard compute nodes and large memory The Lustre file system provides an aggregate bandwidth of 25 GBps (read) and 20 GBps (write). HEMI has access to all of MARCC, but also specifically owns a “condo” for use as needed. LEARN MORE
100 Teraflop Graphics Processor Laboratory (GPL) The GPL facility contains 96 C2050 Fermi graphics cards and 12 C2070 Fermi graphics cards. The host nodes are on the QDR infiniband network for the HHPC as are fileservers with several hundred terabytes of storage. This allows heterogeneous computations both clusters. Hopkins has recently been named a Center of Excellence by nVidia because of this cluster, the Datascope, and other innovative uses of graphics processing cards. LEARN MORE
Data Storage HEMI has 80 TB of storage space available on our dataservers, with an additional 12 TB of back-up storage for data exchange servers and backups. We have specialized software and tools for the archival, curation and search of big data, as well as a variety of data analytics suites. In broad terms, we bring the computational analysis to the data when big data is involved.
Visualization servers The HEMI labs have two Dell quad-core Linux-based desktop servers for visualization of data intensive images. These use NVIDIA graphics cards.
Software packages and development Software packages available in the HEMI lab include: Visit, Uintah, Abaqus, LS-Dyna, Paraview, Atomeye, Gimp, Emacs, LaTeX, Microsoft Visual C++ and associated Visual Studio Tools. We perform software development in a Gitlab environment, teaching students about version control and co-development.
