项目摘要

Description: Under this project scientists from the U. S. and India plan to develop reliable methods of predicting compressive strength of laminated structures when known faults of delaminations exist. Specifically the scientists, Dr. J. N. Reddy of Virginia Tech in Blacksburg, VA, and Dr. A. V. krishna Murty of Indian Institute of Science (IISc) in Bangalore, plan to develop methods of predicting sublaminate instability, delamination growth and residual strength of laminated composite panels subjected to compressive loads. The interaction between the two scientists and their associates is aimed at development of methods for the design of fibre reinforced composite laminates subjected to compressive loads. The work will be primarily theoretical but will build on results of experimental data already generated at the IISc. Scope: Composite materials are increasingly used in a variety of structures in areas as diverse as medical prosthetic devices, electronic appliances, sports equipment, automative parts and high performance space and underwater structures. A limiting factor on their load capacities is the presence of small delaminations and their progress under certain loads. The research is timely, important and of both scientific and practical benefit. The two collaborating teams possess outstanding complementary capabilities to study the problem and the behavior of such materials. The research is likely to benefit both India and the U. S.

描述：在这个项目中，来自美国和印度的科学家计划开发可靠的方法来预测层压结构在已知的分层断层存在时的抗压强度。具体来说，这两位科学家是弗吉尼亚州布莱克斯堡弗吉尼亚理工大学的J. N.雷迪博士和班加罗尔印度科学研究所的A. V.克里希纳·莫蒂博士，他们计划开发一种方法，预测复合材料层压板在压缩载荷作用下的亚层不稳定性、分层生长和剩余强度。两位科学家和他们的同事之间的互动旨在开发纤维增强复合材料层压板承受压缩载荷的设计方法。这项工作将主要是理论性的，但将以印度科学院已经产生的实验数据的结果为基础。适用范围：复合材料越来越多地应用于各种结构，如医疗假肢装置，电子电器，运动器材，汽车零部件以及高性能空间和水下结构。其承载能力的一个限制因素是小分层的存在及其在一定载荷下的进展。该研究具有时效性和重要性，具有科学和实用价值。这两个合作团队在研究这些材料的问题和行为方面具有出色的互补能力。这项研究可能对印度和美国都有利。
