Dr. Mayercsik specializes in the durability and mechanical properties of construction materials, particularly cement-based materials. His expertise includes concrete’s freeze/thaw resistance, concrete mix design, self-consolidating concrete, geopolymers, and blast-resistant concrete and composites.His expertise also includes multi-scale modeling, testing, and evaluation of the structure and properties of cementitious materials. Dr. Mayercsik has experience in studying materials via quantitative image analysis, optical microscopy, and x-ray microtomography, and also modeling materials using continuum mechanics, fracture mechanics, and poromechanics.

Prior to joining Exponent, Dr. Mayercsik was a graduate research assistant at the Georgia Institute of Technology, where he earned a Ph.D. in civil engineering with a minor in materials science. His dissertation work focused on the influence of multi-scale void space on cementitious materials’ response across length and time scales. As part of this research, Dr. Mayercsik investigated the role that flaws play in governing high strain-rate (i.e., blast and impact loading) response of concrete, including dynamic testing using a Kolsky bar and modeling using fracture mechanics. He also developed a poroelastic model to describe the evolution of stresses which develop in concrete during repeated freezing and thawing cycles, and introduced a new spacing factor for entrained air voids in concrete which can be used to predict concrete’s resistance to cyclic freeze/thaw. Dr. Mayercsik’s academic background includes graduate coursework in concrete design; finite element analysis; structural dynamics; structural reliability; elastic wave propagation; durability of concrete; quantitative characterization of microstructure; statistical methods. As a Sam Nunn Security Fellow, Dr. Mayercsik also explored issues at the nexus of science, technology, and public policy.

Dr. Mayercsik taught statics as the instructor-of-record at the Georgia Institute of Technology, and also served as a lecturer for several graduate courses on the properties and durability of construction materials.
