ASTM D3163 Lap Shear Specimen

Plastic lap shear specimens used in adhesive testing by ASTM D3163 (Determining Strength of Adhesively Bonded Rigid Plastic Lap-Shear Joins in Shear by Tension Loading). The standard specimen size is 1" x 4" x 0.010", but these dimensions can be changed based on the yield point of the plastic material used.  The plastic specimens are adhered in pairs at one overlapped end; this pair of specimens is the lap shear specimen. These lap shear specimens are similar to those used in ASTM D1002.
