STRUCTURAL MECHANICS. Expert has expertise in all aspects of structural mechanics. He has consulted with many federal agencies and private firms on diverse structural problems. He taught undergraduate and graduate courses in engineering mechanics and structural analysis and design while a professor at the University of Nebraska. Because of his academic and industrial experience, Expert offers his clients comprehensive and effective techniques to solve their problems.

FINITE ELEMENT ANALYSIS; DEFORMATION ANALYSIS; ANSYS SOFTWARE. A major portion of Expert's career has involved applying finite element techniques to engineering systems analysis and design. He developed a finite element model using ANSYS to study the inelastic deformation process of a solar dish collector surface under fluid pressure. He evaluated the crash-worthiness of several Kansas DOT roadside barrier designs under vehicle impact using computer simulation. He also identified the path of the progressive failure of a surge tank using finite element modeling for a paper-making factory.

STRUCTURAL DYNAMICS; VIBRATION TESTING, MECHANICAL VIBRATION; ANALYSIS & MODELING. Expert is an expert in structural dynamics and mechanical vibration. He has extensive experience in automated data acquisition systems using microprocessor-based data loggers. His doctoral research quantified the dynamic loading on stadium structures due to spectator movements. The results are still widely used by stadium designers. He monitored the wind-induced forces on a transmission line for the Omaha Public Power District. He also conducted vibration tests to determine the natural frequencies, mode shapes and damping ratios of stretched membrane heliostats for the Solar Energy Research Institute.

STRUCTURAL ANALYSIS; STATICS. Expert has expertise in the fields of static and dynamic structural analysis. He has extensive experience in the areas of structural design, utilizing materials such as steel, reinforced concrete, masonry, and timber. In the field of dynamic analysis, he has worked with earthquake, wind, and other mechanical vibration problems.

MECHANICAL BEHAVIOR MODELING. Expert has extensive experience in applying ADINA, SAP90, DYNA/NIKE, and ANSYS in engineering modeling and problem-solving.


Expert may consult nationally and internationally, and is also local to the following cities: Omaha, Nebraska - Lincoln, Nebraska - Sioux City, Iowa - Council Bluffs, Iowa
