碩士 === 逢甲大學 === 機械工程學所 === 94 === The characteristic of its structure laminated composite plate with an Elliptial hole, while building up model necessarily needing to first understand laminate composite material the stress around distribute in the condition. Because an Elliptial hole under loaded as the structure investigate the stress distribution and the stress concentration factor around an Elliptial hole of a laminated composite plate with an Elliptial hole. The laminated composite plate under loads behavior then the maximum normal stress as 90° , and the maximum compressive stress as 0° around an Elliptial hole . The objective of this paper inquires to effect of the fiber ply orientations under loaded laminated composite plate with an Elliptial hole investigate the stress distribution around an Elliptial hole by using ANSYS Finite Element program. The laminated composite plate with an Elliptial hole under loaded behavior analysis consult the basis in the future. The laminated composite plate with an Elliptial hole under loaded investigate the stress distribution and the stress concentration factor can change because around an Elliptial hole go to the plate of the distance of size. The stress distribution and the stress concentration factor obvious , so all strength isn’t ideal. The Quasi-Isotropic laminated composite plate with an Elliptial hole laminate ply way effect all composite plate strength. All laminated plate thickness isn’t change and changed every a laminated thickness. Example： ， laminate ply. Each fiber ply is the same for the stress distribution as under loaded condition. Two kinds of Quasi-Isotropic laminated composite plate comparisons , , both 0° layer in order to mainly bears the stress structure, but have the more fiber ply. Therefore 0° layer the stress distribution and the stress concentration factor comparisons , and laminated 0 ° layer the stress distribution and the stress concentration factor seems to is lower.
