Nathan P. Mayercsik, Ph.D., P.E.

Senior Engineer

Dr. Mayercsik is a consultant in the Buildings & Structures practice for issues related to the design, construction, and performance of various constructed improvements in residential, commercial, and public spaces. Dr. Mayercsik has specialized experience 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. He has evaluated architectural precast and architectural cast-in-place concrete, historic concrete structures, residential and commercial concrete pavements, concrete slabs and foundations, stucco, concrete and shotcrete swimming pools, and concrete parking structures. Dr. Mayercsik has experience in multi-scale modeling, testing, and evaluation of the structure and properties of cementitious materials. He has studied materials via quantitative image analysis, optical microscopy, and x-ray microtomography, and has also modeled materials using continuum mechanics, fracture mechanics, and poromechanics.

Dr. Mayercsik has consulted on large wind and hail losses involving glazing systems, wood composite siding, and concrete tile, built-up, single ply, and asphalt composition roofing materials. He has experience evaluating structures damaged by impact from vehicles and trees. Dr. Mayercsik has also evaluated construction injuries involving falling objects, falls from heights, and cement burns. He has also evaluated the potential contribution of building code noncompliance to slips, trips, and falls.

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

As a Sam Nunn Security Fellow, Dr. Mayercsik also explored issues at the nexus of science, technology, and public policy. This included evaluating policy, technology, and implementation (PTI) studies to understand the path that historic and contemporary technologies have undergone from conception to adoption.
