|Title:||Failure analysis of serial pinned joints in composite materials|
|Abstract:||In this paper, failure load and failure mode of woven glass epoxy composite plates with one and two serial pinned joints are analyzed experimentally and numerically. Two variables are investigated during analyses; the distance from the free edge of the plate to the diameter of the first-hole (<i style="">E/D</i>) ratio, and the width of the specimen to the diameter of the holes (<i style="">W/D</i>) ratios. Experiments are carried out according to the ASTM D 953<sup>1</sup>. Numerical study is performed by means of ANSYS finite element analysis program. Yamada Sun failure criterion is used for failure analyses. Mechanical properties of the composite material are obtained from the ASTM standards. The results showed that maximum failure load is obtained at <i style="">E/D</i>=4 and <i style="">W/D</i>=4. A good agreement is found between experimental results and numerical predictions.|
