    STUDY ON INFLUENCE OF PROCESSING TECHNOLOGY TO RESIDUAL STRESS FOR AERONAUTICAL PMMA BY PHOTOELASTICITY by SHANG Wei, YANG XiaoJing, ZHANG LiNa

    Published 2015-01-01
    “…The damage of the aeronautical PMMA is mainly due to the fatigue cracking leaded by the residual stress.Residual stress will produce the orientated segment or group in the aeronautical PMMA which produce the birefringence effect. In this paper,based on the birefringence effect,the digital phase-shift photoelasticity is used to test the residual stress for drilling the hole. …”

    Influence of the Zn2+ concentration on the defect structure and optical properties in Zn:Fe:Cu:LiNbO3 crystals by Zhehua Yan, Li Dai, Shunxiang Yang, Zesheng Ji

    Published 2025-01-01
    “…The effects of doped ions of Zn2+, Fe3+, and Cu2+ on crystal lattice parameters and defect structure were characterized by XRD and inductively coupled plasma atomic emission spectrometer (ICP-AES), and the optical homogeneity was characterized by the birefringence gradient method. The x-ray powder diffraction experiments reveal that the crystal lattice structure remains unaffected by doping. …”
