Vladimir Valentekovich
Vladimir Valentekovich

Vladimir Valentekovich teaches about pyrotechnic and other forms of shock testing, measurement, analysis and calibration and consults in these fields. He s a graduate of UCLA with his Bachelor and Masters of Science in Mechanical Engineering. He worked as a Senior Test Engineer in Structural Dynamics, specializing in pyrotechnic shock, at Wyle Laboratories, El Segundo.
Vladimir was responsible for quantifying and publishing the high velocity, short duration stress wave resultant in near-field pyroshock, as referenced in the IES Recommended Practice 012.1 Handbook for Dynamic Data Acquisition and Analysis, Appendix A, Pyroshock and the 5th ed. Harris and Piersol Shock and Vibration Handbook, Chapter 26 Part II. Vladimir received the SAVIAC 64th Symposium Henry Pusey Award for this work in 1994.
Wyle Laboratories then was the first independent contractor to do pyroshock qualification testing using the Tomahawk Cruise Missile U/RGM-109D flight structure: from instrumentation, specifying the data acquisition system, placing the charge, to acquiring and analyzing the resultant data. Valentekovich developed many pyrotechnic shock test methods still used at Wyle. He continues to develop alternate pyro shock methods and test equipment including mechanical impact and ballistic shock simulations.
Vladimir currently consults for aerospace and defense firms who seek to design, perform and complete meaningful dynamics test programs.

Kevin Howard
Kevin Howard

Kevin Howard is a talented instructor of short courses in the field of packaging engineering. He is one of fewer than 500 people in the world with both BS and MS degrees in packaging (both from Michigan State University). Kevin specialized in distribution packaging and testing in school and has applied this knowledge over the past 25 years to generate some of the largest cost savings in packaging history. Over his 17 years of work at Hewlett-Packard, Kevin forged several new concepts on how best to combine his interests in
packaging, product design, supply chain logistics procurement, customer assurance and testing into a unified, teachable approach to (1.) gaining the lowest possible landed costs with (2.) the highest quality necessary. Introduced at several conferences as a particularly innovative thinker, Kevin prides himself on his ability to communicate with newcomers to packaging concerning the depth and breadth of packaging knowledge, supply chain logistics, material handling methodologies and dynamics testing.
Testing expertise: Kevin focused on testing theory and methods during graduate school, where he was the teaching assistant for two years in the class on shock and vibration testing. He spent one summer interning for MTS Systems, which at that time was the largest manufacturer of servohydraulic shaking equipment. His first job out of school was with Whirlpool Corporation, where he helped start their first shock and vibration lab. He then became a consultant. His assignments included teaching at the first school of packaging in China, focused on distribution packaging and testing. While at HP, Kevin was instrumental in helping re-write both corporate and divisional test manuals. Modifying HP’s testing led to lower failures in the field and lower packaging costs overall…an unusual combination
