Expert has extensive experience designing rubber components for a diverse range of industries. For example: 1) oil field applications such as flexelements for tension leg platforms, blowout preventers, and downhole packers, 2) aerospace applications such as control rod bearings, LED-LAG dampers, landing gear systems, rotor blade retention thrust bearing for helicopters, and engine mounts and isolators for aircraft, 3) military applications such as submarine deck mounts and pipe hangers, shipping containers, and electronic isolators, and 4) general industrial application such as shock and vibration mounts, high pressure seals, and diaphragms. Expert understands the unique design problems associated with laminated rubber bearings, vibration isolators, and very large rubber parts. He has expertise with product fatigue and failure analysis, shock and vibration analysis, as well as finite element analysis techniques for predicting rubber strains, stiffness, heat generation, stability.

Expert has expertise with high-pressure molding, molding laminated rubber designs, molding thin rubber sections, the unique problems of molding very large rubber products, and rubber adhesive bonding.

Expert has expertise using finite element analysis to model the rubber for both design and manufacturing applications. Design applications include modeling the rubber, reinforcing metals, and attachment hardware undergoing multiaxial loadings. Manufacturing applications include modeling the rubber component and mold tool during the vulcanization cycle. Analysis of results allow him to predict rubber strains, bond stresses, attachment hardware stresses, stability, heat generation and total cure state, temperatures of bond formation, rubber shrinkage stresses, minimum cure time, and mold metal stresses.

Expert is familiar with common rubber testing, especially those involving ASTM and military specifications and what tests are of value and which are not. The emphasis of his experience is on tests for complex modulus, damping capacity, low temperature flexibility, adhesive strength, fatigue, crack growth, and material characterization for finite element analysis.

Expert has expertise with natural rubber (NR) and familiarity with silicone, EPMD and nitrile compounding for fatigue resistance, high or low temperature resistance and variable damping.

Expert may consult nationally and internationally, and is also local to the following cities: Tucson, Arizona
