CMS 9800308 PI: A. Pelegri Rutgers U ABSTRACT An Electronic Speckle Pattern Interferometry system and a Tele-Microscope are acquired to study the onset of intraply delamination, delamination growth in laminated composite structures, evaluation of shear stresses in delaminated composite beams, and assessment of martensite plates orientation during ohase transformation in shape memory alloys. These investigations help in understanding scale effects in testing and damage of composites, developing scale laws such that data generated at subscale level can be used to predict the behavior of full-scale components, and providing insight into damage initiation and phase transformation mechanisms. Application areas include electronic packaging, structronics, aerospace structures, and optical fibers. ***

摘要：利用电子散斑干涉测量系统和远程显微镜研究了层状复合材料结构中层间分层的发生、分层的生长、分层复合材料梁中的剪切应力评估以及形状记忆合金中oase转变过程中马氏体板取向的评估。这些研究有助于理解复合材料测试和损伤中的尺度效应，发展尺度规律，以便在亚尺度水平上生成的数据可用于预测全尺寸部件的行为，并提供对损伤起始和相变机制的见解。应用领域包括电子封装、结构电子学、航空航天结构和光纤。＊＊＊
