In this study, we explore various factors for design of composite structures with ply drops. These factors include: thicknesses, ply stacking sequences, ply drop geometries and manufacturing …

In this paper, the influence of three most important design parameters, viz. number of plies dropped-off at a single station, distance between successive drop-offs (stagger distance) and …

在复合材料层合板中，为了根据载荷要求调整层压板的厚度，常会发生削层。 本例演示复合板的削层建模。 所分析的面板具有对称的角铺设层，其中包括三个部分：厚部分、锥形部分和薄部 …

2001年1月1日 · In this paper, the influence of three most important design parameters, viz. number of plies dropped-off at a single station, distance between successive drop-offs …

2001年4月1日 · Laminates with plies dropped along more than one direction are of frequent occurrence in laminated structural components. These ply drops occur because of the …

Ply drop-offs should not be less than 20 to 1 in the load direction. i.e. if a single ply is .010 in thick the minimum drop-off spacing should be one ply every 0.2in. Skin ply drop-offs should not …

2015年1月30日 · 复合材料制件过渡区由铺层减层自然形成,但是过渡区减层截面形状有多种样式。试验件样式如图1示,试验件尺寸见图2。试验件过渡类型以及模型参数见表1。过渡类型A、B …

2021年1月26日 · Finally, the optimization strategy revealed that the optimal drop-off location that minimizes the strain and maximizes the natural frequency is the ply drop-off located of the end …

composite structures with ply drops. The SST describes the sequence of ply-drops ensuring the transition between a thick guide laminate and a thinner one. A blended design is represented …

Ply drop means the resin rich regions created due to abrupt ending of individual plies within the set of plies. This research is focused on understanding and quantifying the effect of these ply …
