I work with: Energy Geoscience and Engineering, Unconventional Shale Science
Dr. Ingraham is currently a Senior Member of Technical Staff at Sandia National Laboratories , working in the Geomechanics department. His Ph.D. work focused on the effect of the intermediate principal stress on failure and deformation band formation in sandstone. His current research focuses on the interaction of proppant with shale, and development of constitutive properties for shale. He has also worked on developing model parameters for domal salt in the Strategic Petroleum Reserve; bedded salt, crushed salt , and surrogate waste for the Waste Isolation Pilot Plant; and determination of elastic, plastic, and poroelastic parameters for shales and sandstones.
An expert in experimental methodology and constitutive model development , Mathew also works on many projects involving traditional engineering materials and systems at Sandia including consulting on the design and test methodology for the Sandia Fracture Challenge. A double blind study looking at testing and modeling ductile materials failing in non – traditional means (tearing). Mathew was elected to the American Rock Mechanics Association Future Leaders program in 2015.
