Areas of Research

Mechanics of materials and manufacturing processes

Current and recent projects include:

Microelectronics Packaging

  • the dependence of solder creep on state of stress, load and temperature
  • solder joint strength prediction
  • thermal fatigue models of plated-through-vias (PTVs) in printed circuit boards and measurements of thermal fatigue life using air cycling and IST tests
  • accelerated thermal fatigue testing and modeling of microelectronic solder joints
  • mechanics of printed circuit board wave soldering and resulting board warpage

Tribology

  • abrasive wear and impact erosion associated with the vibratory finishing process
  • abrasive jet micro-machining of glass, silicon and polymers for microfluidic and opto-electronic applications

Adhesive Bonding

  • automotive structural adhesive bonding including fracture mechanics, fatigue, durability, and the failure of adhesive joints accompanied by large-scale adherend yielding

Wood-based Materials

  • analysis of metal-plate wood truss connections
