Gage Selection Case
Histories
|
Three examples are given of the
Gage-Selection Procedure
in representative stress analysis situations. An
attempt has been made to provide the principal
reasons for the particular choices which are made. It
should be noted, however, that an experienced stress
analyst does not ordinarily proceed in the same
step-by-step fashion illustrated in these examples.
Instead, simultaneously keeping in mind the test
conditions and environment, the gage installation
constraints, and the test requirements, the analyst
reviews
Standard Gage Series
table, used in conjunction with Catalog 500,
Micro-Measurements Precision Strain Gages
, and quickly segregates the more likely candidates
from among the available gage-pattern and series
combinations in the appropriate sizes. The selection
criteria are then refined in accordance with the
particular strain-measurement task to converge on the
gage or gages to be specified for the test program.
Whether formally or otherwise, the knowledgeable
practitioner does so in the light of parameter
selection considerations such as those itemized in
the
Strain Gage Selection
Checklist.
