Numerical and Experimental Investigation of the Effect of Different Orientation Angles on Crash Behavior of Composite Hat Shape Energy Absorber
Car body lightening and crashworthiness are two important objectives of car design. Due to their excellent performance, composite materials are extensively used in the car industries. In addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. Hat shape energy absorber is used in car’s doors for side impact protection. The aim of these numerical models and expe...

متن کاملOn the flexural properties of multiscale nanosilica/E-glass/epoxy anisogrid-stiffened composite panels
In the present study, multiscale nanosilica/E-glass/epoxy anisogrid composite panels were investigated for flexural properties as a function of nanosilica loading in the matrix (0, 1, 3 and 5 wt.%). The surface of the silica nanoparticles was firstly modified with 3-glycidoxypropyltrimethoxysilane (3-GPTS). The fourier transform infrared (FTIR) spectroscopy revealed that the organic functional ...
متن کاملExperimental Investigation and Numerical Simulation of the Mechanical Behavior of a Novel Honeycomb Core Sandwich Panels Formed by Hydroforming Process
Sandwich panel with central core honeycomb aluminum as one of the main shielding structures because of their high strength-to-weight ratio and improved energy absorption capacity, has been attracted the attention of many researchers and practitioners in recent years. This paper initiates and presents a new type of central core honeycomb formed by hydroforming process. The study is augmented by ...
