Abstract. During the forming of woven fabrics, different multiaxial stress states can occur, depending on given process conditions and complex deformation mechanisms interwoven structure textile. Particularly under constrained conditions, induced e.g. by blank holders or adjacent metal layers in fiber-metal-laminate (FML) forming, may include in-plane compression. A hyperelastic, invariant-base...

The effect of changing operating temperature on the compressive response of IM7/PETI5 composite laminates is investigated within this paper. The three temperatures evaluated for this study were –129C, 21C, and 177C, a spectrum from cryogenic to an elevated operating temperature. Laminate compressive strength property testing was conducted using the Wyoming Combined Load Compression fixture to g...

When a laminate of a thin metal film on a tough polymer substrate is stretched, the metal film may rupture at strains ranging from a few percent to a few tens of percent. This variation in the ductility of the metal film is modulated by the adhesion of the metal/polymer interface. To study this modulation, here we use the finite element method to simulate the co-evolution of two processes: debo...

In this study, SHS was used to produce metal-intermetallic-ceramic laminate AlMg6-NiAl-TiC composite. The experiment conducted without a cylindrical powder pellet holder produced no joint between the NiAl and AlMg6 sheet. On other hand, inside (CPPH) with blind hole joint. It found that sheet had temperature of 400–550 °C across its entire thickness during SHS. study microstructure energy-dispe...

The exploration of two-dimensional solids is an active area of materials discovery. Research in this area has given us structures spanning graphene to dichalcogenides, and more recently 2D transition metal carbides (MXenes). One of the challenges now is to master ordering within the atomic sheets. Herein, we present a top-down, high-yield, facile route for the controlled introduction of ordered...

The growth of the aerospace industry has motivated the development of alternative materials. The fiber-metal laminate composites (FML) may replace the monolithic aluminum alloys in aircrafts structure as they present some advantages, such as higher stiffness, lower density and longer lifetime. However, a great variety of deformation modes can lead to failures in these composites and the degrada...

Stress wave propagation in a metal–plastic bonded laminate immersed fluid is investigated based on linear viscoelastic theory. The reflection spectrum theoretically derived for normal incidence. For the incidence from plastic layer, amplitude of shown to have local minima at resonance frequencies every single layer. Resonance metal layer leads destructive interference reflected components, whil...
