Measurement of Variation in Fracture Strength and Calculation of Stress Concentration Factor in Composite Laminates with Circular Hole
In this research, residual strength and stress concentration factor of laminated composites with a circular open hole are studied analytically, numerically and experimentally. The numerical study was carried out using the finite element method. Moreover an analytical study was carried out with developing of point stress criterion. Mechanical testing was performed to determine the un-notched ten...
متن کاملIdentification of Orthotropic Plate Stiffness Using Open Hole Tensile Test
Identification of mechanical parameters is still a challenge on real structures. With the improvement of optical full field measurement techniques, it becomes easier, but in spite of many publications showing the feasibility of such methods, experimental results are still scarce. We present here a first step towards a global approach of mechanical identification for composite materials. The cho...
متن کاملA Unified Model for Predicting the Open Hole Tensile and Compressive Strengths of Composite Laminates for Aerospace Applications
The open hole tensile and compressive strengths are important design parameters in qualifying fiber reinforced laminates for a wide variety of structural applications in the aerospace industry. In this paper, we present a unified model that can be used for predicting both these strengths (tensile and compressive) using the same set of coupon level, material property data. As a prelude to the un...
متن کاملStress and Load-displacement Analysis of Fiber- Reinforced Composite Laminates with a Circular Hole under Compressive Load
This paper is focused on the analysis of stress-strain and displacement for compressive load on the fibrereinforced composite laminates. Three different orientations of fibers are analyzed with and without the circular cut-outs. Also different dimensions of circular cut-outs are applied on the laminates at different compressive loading conditions. This analysis is carried out using the finite e...
متن کاملComparative Analysis of Drills for Composite Laminates
The characteristics of carbon fibre reinforced plastics allow a very broad range of uses. Drilling is often necessary to assemble different components, but this can lead to various forms of damage, such as delamination which is the most severe. However, a reduced thrust force can decrease the risk of delamination. In this work, two variables of the drilling process were compared: tool material ...
