We measure three-dimensional stress ﬁeld of RP model having a V-notch. RP model (Elastic modulues E = 3317 MPa, 9.3 × 7.7 × 50 mm3 having a V-notch) is made of acrylic transparent resin and tracer particle (averaged diameter: 60μm) are dispersed. The model is subjected to the static load (100 N) at the middle. Firstly, three-dimensional deﬂection is measured by using digital holographic PTV (Particle Tracking Velocimetry). Finally, three-dimensional stress ﬁeld of RP model is visualized as a diﬀerential value of the deﬂection ﬁeld.
