9870947 Shukla将获得一个高速成像系统，该系统由一个高速、连续访问分幅相机和一个与相机一起操作的相干、准直、单色和脉冲光源组成。 该系统是光力学实验室高速成像能力的根本升级，将支持工程和科学方面的研究与发展。 这种新型的高速成像系统将用于研究各种高加载速率和应力波主导的物理现象。 新的高速成像系统的先进功能将被用来调查的陶瓷-金属界面的动态载荷下的灾难性脱粘。 真实的时间实验将使用基于干涉的光学技术，如相干梯度传感。 莫尔条纹和Twyman-Green干涉法研究陶瓷/金属双材料界面断裂的各个方面。 动态加载可通过单点弯曲配置中的射弹撞击或通过炸药的引爆来实现。

9870947ShuklaA high -speed imaging system consisting of a high-speed, continuous access framing camera and a coherent, collimated, monochromatic and pulsed light source operated in conjunction with the camera is to be acquired. This system represents a fundamental upgrade of the high-speed imaging capabilities of the Photomechanics Laboratory and would support research and development in engineering and sciences. The new high-speed imaging system would be utilized to investigate various high loading rate and stress wave dominated physical phenomenon. The advanced capabilities of the new high speed imaging system will be utilized to investigate catastrophic decohesion of ceramic-metal interfaces subjected to dynamic loading. Real time experiments will be conducted using interferometry based optical techniques such as Coherent Gradient Sensing. MoirÚ and Twyman-Green interferometry to investigate various aspects of the fracture of ceramic/metal bimaterial interfaces. Dynamic loading would be achieved either by projectile impact in a one point bend configuration or by detonation of explosive.
