February 23 @ 8:30 am - 12:30 pm

Private Webinar:  Physics of Failure, Electronic and Mechanical Failure Modes and Models by Dr. Alec Feinberg

Please note, this course is not open to others, as it is a private event.  If you are interested in having this course presented to your team please contact us for more information.  Our courses can be presented to your team live at a time convenient for you!

There are many aspects to the science of physics of failure. In this course we approach the subject by dividing it up into two main sections:

Physics of Failure

  • Mechanical Failure Modes & Models
  • IC & Electronic Failure Modes & Models

This 4 hour course is an in-depth approach to physics of failure.
It is designed for the engineer who wants a good knowledge base including the state-of-the-art in this area.
The following outline provides an overview for each section

Physics of Failure Introduction

  • Four main types of aging

 
Physics of Failure Tools (Mechanical Failure Modes & Models)                                                                                                       
o   Mechanical Plastic Deformation: Elastic deformation, yielding (with vibration) and ductile rupture (with shock) material considerations
o   Creep & cumulative creep fatigue material considerations, viscoelastic creep, creep acceleration factor
o   Excessive wear; friction & lubrication – types of wear, vibration wear, material selection & hardness, wear acceleration factor
o   Cyclic Fatigue: Exact method for damage estimation (derivation using thermodynamic work)
o   Miner’s approximation – derivation, why it is an approx., stress concentration
o   SN curves – material selection
o   Fatigue (SN curves, Basquin’s and Coffin-Manson -high and low cyclic fatigue, Loading Types – stress corrections, Facture Mech. Vibration fatigue, when SN Curves not available)
o   PCB fatigue life – Circuit board component fatigue life model analysis –Steinberg Method (sine and random)
o   Thermal cycle (strain, fatigue, acceleration factors derivations for Coffin-Manson & Modified, Norris-Landzberg)

About your instructor:
Dr. Alec Feinberg
is the founder of DfRSoft. He has a Ph.D. in Physics and is the principal author of the books, Design for Reliability (DfR) and Thermodynamic Degradation Science: Physics of Failure, Accelerated Testing, Fatigue, and Reliability Applications. These books are written in an industrial environment, and are very practical. Alec has a logical approach to the DfR processes using a stage gate method since products are develop in these phases. Alec uses this method in his reliability training classes as well found on the DfRSoft website. Alec is also the principal developer for DfRSoftware which is the most thorough reliability tool currently available and is also used to accelerate learning in his training classes. Alec’s industrial experience has allowed him to provide extensive reliability engineering services in diverse industries (AT&T Bell Labs, TASC, M/A-COM, Tyco Electronics, and Advanced Energy) for over 35 years on solar, thin film power electronics, defense, microelectronics, aerospace, wireless electronics, and automotive electrical systems. He has provided training classes in Design for Reliability & Quality, Shock and Vibration, HALT, Reliability Growth, and Electrostatic Discharge. Alec has presented numerous technical papers and won the 2003 RAMS Alan O. Plait best tutorial award for the topic, “Thermodynamic Reliability Engineering.”
