Layers of thin metallic sheets and fiber-reinforced composite layers bonded together is known as fiber metal laminates (FMLs). In the current study, titanium Ti–6Al–4V sheets are used with thicknesses 0.2 mm, 0.4 mm and, 0.6 mm along with layers of unidirectional glass-fiber reinforced composite to produce FMLs and the tensile response of these laminates are examined. Four different stacking sequences of FMLs have been considered exhibiting the same thickness for the total metal layer and the hand layup process is used to prepare these laminates. An orthotropic plasticity theory of macro mechanical type and classical laminated plate theory are considered to model the elastic-plastic type of behavior of titanium-based FMLs. A plastic potential function based on three parameters is used to the model the orthotropic plasticity. Behavior with linearly elastic and orthotropic elastic-plastic types is assumed for the layers of glass composite and titanium, respectively in the laminated plate theory. The results show that the initial modulus of FMLs has not been influenced by the sequence of the layup, while this sequence of layup does considerably affect the response of FMLs following ultimate strength. The properties of FMLs such as failure strain and toughness which are important parameters from a design point of view of FMLs can be altered to absorb energy at dissimilar rates, i.e., by insulating the composite layers from each other by metallic layers in case of FMLs 3/2–0.4, 4/3–0.2(O) and 4/3–0.4(O). The model with orthotropic plasticity is found to be precise up to the total strain level of 2.1%, i.e., close to the failure of composite layers within FMLs, when compared with results measured from experiments. The behavior with stress-strain predicted by laminated plate theory also finds realistic up to the total strain of 2.1% to describe the corresponding behavior obtained from experiments.

粘合在一起的薄金属板层和纤维增强复合材料层称为纤维金属层压板（FML）。在当前的研究中，使用厚度为0.2 mm，0.4 mm和0.6 mm的Ti-6Al-4V钛板以及单向玻璃纤维增​​强复合材料层来生产FML，并检查了这些层压板的拉伸响应。已经考虑了四种不同的FML堆叠顺序，它们的总金属层厚度相同，并且采用手工铺层工艺来制备这些层压板。宏观力学类型的正交各向异性可塑性理论和经典的层压板理论被认为是模拟钛基FML行为的弹塑性类型的模型。基于三个参数的塑性势函数被用于对正交各向异性塑性进行建模。在层压板理论中，分别假设玻璃复合材料和钛层具有线性弹性和正交各向异性弹塑性类型的行为。结果表明，FML的初始模量不受铺层顺序的影响，而该铺层顺序确实会极大地影响FML遵循极限强度的响应。从FML的设计角度来看，FML的特性（例如失效应变和韧性）是重要参数，可以对其进行更改，以不同的速率吸收能量，即在FML的情况下，通过金属层使复合层彼此绝缘3 /2–0.4、4/3-0.2(O）和4 / 3-0.4（O）。发现具有正交各向异性可塑性的模型可以精确到高达2.1％的总应变水平，即接近FML内复合层的破坏，与实验测得的结果相比。叠层板理论预测的应力应变行为也可以找到高达2.1％的总应变，以描述从实验中获得的相应行为。
