The aim of this study is to investigate effects of isothermal aging on mechanical properties of fiber metal laminates (FMLs) and glass/epoxy composites. For this purpose, both materials were fabricated using the wet lay-up manufacturing technique under vacuum pressure. Both the glass/epoxy composites and the FML specimens were then subjected to isothermal aging (130°C, dried air) for up to 5 we...

The predominant use of FBG sensors to characterize the residual stress state in composite materials date does not permit absolute strain measurements. reason for this is loss connection between sensor and laminate during phase transitions resin. Thus, points significant changes measurement signal (e.g. bonding temperature) need be used evaluation. For fiber metal laminates (FML) however, gages ...

The objective of this study was to design custom-made prosthesis in a certain population, the morphometry needs to be measured. The results of this study were expected to provide basic data to design the ideal size of the total knee arthoplasty prosthesis for Indonesian population. This was an anthropometric study conducted on 100 healthy Indonesian population based on Computer Tomographic (CT)...

This paper proposes an agent with particle swarm optimization (PSO) based on a Fuzzy Markup Language (FML) for students learning performance evaluation and educational applications, and the proposed agent is according to the response data from a conventional test and an item response theory. First, we apply a GS-based parameter estimation mechanism to estimate the items parameters according to ...

Abstract Fiber metal laminates (FML) are hybrid materials consisting of and composite layers. They have great mechanical fatigue properties. However, interface between layers can be critical for their final In this paper, process determination some fracture parameters in unusual FML material is described. Experimental tests following ASTM norm were conducted using Double Cantilever Beam (DCB). ...

The importance of energy preservation in wireless sensor networks is long established, and a number of maximum lifetime routing schemes exist in the literature. Many of the existing online routing schemes are based on the use of some edge-weight functions, but those schemes exhibit diverse performances in terms of the obtained lifetime results. The major contribution of the present work is to c...

Abstract. Matrix accumulations, buckling and tearing of fibers metal sheets are common defects in the deep drawing fiber laminates. The previously developed in-situ hybridization process is a single-step method for manufacturing three-dimensional laminates (FML). During FML, low-viscosity thermoplastic matrix injected into dry glass fabric layer using resin transfer molding process. concurrent ...
