Energy Methods and Damage Analysis

in Traffic Crash Reconstruction

(40 Hours)

For many traffic crash reconstructionists, the topic of energy can

be intimidating, mysterious or down right scary. Because of this,

reconstructionists shy away from utilizing energy methods in their

analysis. This course will help de-mystify the concept of energy

and present energy-based methods and techniques to use in

analyzing traffic crashes.

During the course, you will learn to view and analyze crashes

from an energy point of view. We will explore energy methods

beginning with the basics and progressing to more advanced

concepts. We will discuss the often-misunderstood topics of

Equivalent Barrier Speed (EBS) and delta-V and you will learn

different ways to analyze collisions, such as damage momentum,

where a traditional conservation of linear momentum may not

be the most appropriate analysis.

We will also explore the topic of crush. We will examine the

basis of the three familiar energy equations that use crush

measurements. Outside projects will provide you with

“hands-on” experience in examining and measuring crash

vehicles and then calculating damage energy and speeds.

This course will help you become more comfortable in utilizing

energy-based methods in your analysis as we examine the

underlying science that computer-based “crash” programs rely

upon. It is an excellent complement to other training courses

that teach you how to use “crash” software.

You should have a firm understanding of the topics of traffic

crash reconstruction and conservation of linear momentum as

well as strong basic math skills.

Topics include:

• Standards, measurements and dimensional analysis

• Understanding and using conversion factors

• Vectors

• Damage momentum and crush analysis

• Crush measuring protocol and measuring techniques

• Outdoor project - interpreting damage and measuring

crush

• Energy concepts and analysis

• Determining appropriate post-impact drag factors

• Understanding EBS and delta-V

• Conservations of linear momentum and delta-V vectors

• Introduction to crush and Hooke’s Law

• Collision analysis using damage momentum

• Understanding and determining stiffness coefficients

• Damage (crush) analysis

• Pole impacts and fracture energy

• Using simultaneous equations to solve in-line collisions

Prerequisite: You must have completed IPTM’s Traffic Crash

Reconstruction course or its equivalent.

Audience: Law enforcement and private traffic crash

investigators, claims adjusters, engineers, attorneys, safety

officers, military investigative personnel
