Strain Measurements on Com posite Materials: Two
Days
Course W66
The two-day strain gage workshop is a hands-on program where each
participant completes three gage installations on fiber
reinforced composites using materials selected for suitability with
these specialized materials.
The programs are conducted by experienced Applications Engineers
using audio-visual aids appropriate to the group size,
including closed-circuit television.
Participants are encouraged to bring their strain gage measurement
questions and problems for discussion.
