摘要： Ballistic failure resistance is imparted to metallic ballistic armor plate by identifying a compressive residual stress profile for mitigating a predetermined ballistic failure mode in a metallic ballistic armor plate component, and imparting the identified compressive residual stress profile to the component by laser peening the component in a treatment mode predetermined with reference to the identified compressive residual stress profile.

摘要： A laser system includes an integrated fiber laser front-end, configured to generate and output a pre-amplified first pulsed laser beam having predefined beam characteristics corresponding to a user defined pulse shape and a user defined pulse width setting selection of a controller. The first pulsed laser beam is generated from a master oscillator which outputs a CW laser beam to a temporal pulse shaper, which modulates the CW laser beam to output the first pulsed laser beam in response to an electrical pulse from an arbitrary wave generator and a DC bias voltage from an automatic modulator bias control circuitry. The first pulsed laser beam is pre-amplified to an output pulsed laser beam for laser peening or laser bond inspection. A beam detector is used to monitor beam characteristics, and to generate an error signal to be sent back as a feedback signal to the controller for adjustments and corrections.

摘要： A laser shock processing treatment is employed to condition the mating surfaces of various fastener elements, such as screws, bolts, splines, keys, and keyways. In a screw, for example, the threaded surface is laser shock processed to form laser shock processed surfaces at the thread root portion of the screw. Regions of compressive residual stresses imparted by laser shock processing are thereby formed and extend into the screw body from the laser shock processed surfaces. In a keyway, for example, the keyway surface is laser shock processed to form laser shock processed surfaces within the keyway. Regions of compressive residual stresses imparted by laser shock processing are thereby formed and extend into the keyway body from the laser shock processed surfaces. The compressive residual stress regions enhance the rigidity and torsional stiffness of the fastener elements and improve their fatigue properties.

摘要： A method and apparatus for increasing the effectiveness and efficiency of laser shock processing of a solid material. The method includes applying an energy absorbing coating to a portion of the surface of a solid material, applying an ultraviolet curable resin to the coated portion of the surface of the solid material, applying an ultraviolet light to the curable resin to form a pellicle over the energy absorbing coating on the surface of the solid material, and applying a transparent overlay to the pellicular portion of the solid material. A pulse of coherent laser energy is directed to the coated portion of the solid material to create a shockwave. After the pulse of coherent energy is directed to the solid material, a high-speed jet of fluid may be directed to the coated portion of the solid material to remove the remaining coating from the solid material.
