Abstract
An apparatus for measuring the strength of a pressure pulse created from a laser peening device. The apparatus is reusable, and includes a pressure-sensitive medium, a back-up disk, and a cap, all disposed within a housing having a removable lid. All components of the apparatus are replaceable, thereby allowing an operator to utilize the apparatus more than once despite the harsh environment of laser peening.
Claims27
A shock pressure gauge for measuring applied pressure in a laser shock peening device, said gauge comprising:
- a back-up disk;
- a cap with an external surface and an internal surface, said internal surface engaging said back-up disk;
- and
- a pressure-sensing element disposed between said back-up disk and said cap.
An instantaneous pressure meter for determining applied pressure in a laser shock processing device, said meter comprising:
- a housing having a base and a removably interlocking lid;
- and
- a pressure-sensing element disposed between said base and said lid.
A shock pressure gauge for a laser shock peening device, said gauge comprising:
- a housing having a base and an interlocking lid;
- a piezoresistive element disposed between said base and said lid, said element providing varying resistance to electricity responsive to pressures applied to said element;
- a first insulating film between said base and said element;
- a second insulating film between said lid and said element;
- a back-up disk disposed between said base and said first insulating film;
- a momentum trap positioned adjacent to said back-up disk;
- and
- a cap disposed between said lid and said second insulating film.
A shock pressure gauge for measuring applied pressure in a laser shock peening device, said gauge comprising:
