Abstract

An analytic model was derived to describe the shock wave attenuation in plexiglass.Experimental measurements were also presented with a well-designed optical fiber sensor based on detection beam deflection.The velocity and pressure of the shock wave were achieved at different distances.Good agreement between the experimental and calculated values of the shock wave pressure was established.
