Simulating Composite Structures
ثبت نشده
چکیده
different physical or chemical qualities — makes them attractive for manufacturing because they are lightweight and high in strength. However, they also pose unique modeling challenges because of their different constituent materials and orientations. The good news is that you can overcome these challenges using the correct tools. Furthermore, composites are being used reliably to solve real-world industry problems, such as in aerospace and energy applications.

متن کاملWave Propagation Analysis in Composite Laminates Containing a Delamination Using a Three-Dimensional Spectral Element Method
A three-dimensional spectral element method SEM was developed for analysis of Lamb wave propagation in composite laminates containing a delamination. SEM is more efficient in simulating wave propagation in structures than conventional finite element method FEM because of its unique diagonal form of the mass matrix. Three types of composite laminates, namely, unidirectional-ply laminates, cross-...
متن کاملThe combined effect of food-simulating solutions, brushing and staining on color stability of composite resins
Objective: This study evaluated the effect of food-simulating media associated with brushing and coffee staining on color stability of different composite resins. Materials and methods: Eighty specimens were prepared for each composite: Grandio SO (Voco), Amaris (Voco), Filtek Z350XT (3M/ESPE), Filtek P90 (3M/ESPE). They were divided into four groups according to food-simulating media for 7 day...
