“…Numerical and experimental study was performed on metal/thin viscoelastic polymer/metal sandwich sheet in V-bending process [15]. V-die bending of the laminated sheets and springback was studied using numerical and experimental approaches [16]. Deep drawing of St/PP-PE/St laminates was investigated using finite element method (FEM) and experiments, and effect of different parameters in deep drawing process is elaborated [17].…”

Al/PP/Al laminated sheets have shown promising properties for different applications from aeronautics to construction. In this paper, an easy and fast springback prediction of Al3105/polypropylene/Al3105 sandwich sheets in air bending process is presented. An analytical formulation for springback prediction is developed based on a wrap around assumption and primary bending theories. Numerical simulation and experiments were carried out for verifications for the effect of punch radius, die opening, and punch stroke on springback. Results show that with an increase in either punch stroke, punch radius or die opening, springback increases. Die opening was found to be the most influential parameter.

“…Since no slip occurred between metal faces and GFRP core during HMD of FMLs, the contact surfaces between the core and the skin were tied together similar to some related numerical studies [6,22–24]. In order to reduce the solution time, the mass scaling factor of 5000 was applied in the explicit solver during the forming stage.…”

It is known that fiber metal laminates as one of hybrid materials with thin metal sheets and fiber/resin layers have limited formability in conventional forming methods. This paper presents an experimental and numerical study for drawability of glass fiber-reinforced aluminum laminates under hydromechanical drawing technique. Fiber metal laminates comprised of a layer of woven glass fiber-reinforced prepreg, sandwiched between two layers of aluminum alloy. In order to produce fiber metal laminates, the laminates were subjected to a sufficient squeezing pressure under a controlled heating time and temperature by using a hydraulic hot press. A hydromechanical tooling equipped with blank-holder force and fluid pressure control system was used to form the initial circular fiber metal laminate blank. Finally, the effect of parameters such as pre-bulging pressure, final chamber pressure, and drawing ratio on process variables was evaluated. Also, the characteristic curve of hydromechanical drawing of fiber metal laminate i.e. chamber pressure in terms of drawing ratio was achieved by means of experimental tests and numerical simulations. The results showed that the maximum drawing ratio of defect-free fiber metal laminates, namely without any tearing, wrinkling, and delamination was obtained at pre-bulging and chamber pressure of 35 and 80 bar, respectively.

Bu çalışmada, alüminyum-karbon elyaf sandviç levhaların V bükme operasyonu neticesinde oluşan geri esneme davranışı deneysel olarak incelenmiştir. Bükme yönünün geri esneme davranışı üzerine olan etkisini incelemek amacıyla farklı bükme yönlerindeki sandviç kompozit levhalar 15°, 30°, 45°, 60°, 75° ve 90° bükme açılarında şekillendirilmiştir. Farklı bükme yönlerinde şekillendirilen sandviç kompozit levhalarda meydana gelen geri esneme değerlerinin birbirine çok yakın olduğu tespit edilmiştir. Ayrıca, T1 (saat yönünün tersinde) bükme yönündeki sandviç kompozit levhaların 75° ve 90° bükme açılarındaki testlerinde alüminyum ve karbon elyaf plakalar arasında açılmalar görülürken, T2 (saat yönünde) bükme yönündeki sandviç kompozit levhaların 75° ve 90° bükme açılarında ise dış taraftaki alüminyum sac levhalarda yırtılmalar oluşmuştur.
