The Effects of a Damage Arrestment Device on the Mechanical Behavior of Sandwich Composite Beams under Four-point Bending

The demand for an insert on composite sandwich structures to aid in the arrestment of face-core delamination is of great need. This research studies the use of a damage arrestment device (DAD) that connects the carbon fiber face sheets to the foam core to find whether an increase in the structural integrity of the sandwich beam results. Experimental analysis was employed to test the samples and...

A Clamped Three-point Bending Setup for Fatigue of Thin Composite Laminates

Usually, fatigue tests on fibre-reinforced composites are performed in uni-axial tension/tension or tension/compression fatigue [1], providing the S-N data. Although bending fatigue tests are not widely accepted as a standard, they are used a lot for research purposes [2] and they do have some important advantages [3]. In case of three-point bending fatigue, the history of bending force versus ...

Cluster Analysis of Acoustic Emission Signals for Carbon/Epoxy Composite in Four-point Bending Test (RESEARCH NOTE)

Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...

Four-point bending evaluation of dentin-composite interfaces with various stresses.

UNLABELLED Fracture properties of composite-dentin beams bonded with a self-etching adhesive were tested following short term pretreatments to simulate potential degradation mechanisms (thermal cycling, immersion in 5% NaOCl, or fatigue cycling). Beams of rectangular cross-section were shaped to a size of approximately 0.87 x 0.87 x 10 mm and placed in a four-point bending apparatus, with the l...

Peridynamic modeling of composite laminates under explosive loading

High velocity impact and shock or blast responses are a critical design characteristic determining sizing of composite parts and, ultimately, weight savings. This study demonstrates the applicability of peridynamics to accurately predict nonlinear transient deformation and damage behavior of composites under shock or blast types of loadings due to explosions. The peridynamic predictions correla...
