    Compression of UHMW sheet in bend

    We are bending a 12"x5"x.125" UHMW extruded sheet around a 4.5" radius. When we do so, the sheet seems to compress and the overall length decreases by 1.8%. Is that really what is happening or is there something obvious we are missing? If it is compressing, over time will the material creep...
