Numerical and Experimental Study of Quasi-Static Loading of Aluminum Closed-Cell Foams Using Weaire–Phelan and Kelvin Tessellations

Study of porous materials, in particular closed-cell foams, has always attracted researchers’ interest due to the advantages these materials offer in applications where low weight, buoyancy, insulation, or energy absorption is of importance. In this study, quasi-static compressive experimental tests are conducted for low-, medium-, and high...

Experimental evaluation of load transfer efficiency of non-dowelled concrete pavements

Generally, joint performance in concrete pavements is evaluated in laboratory by applying dynamic loads that require large scale experimental setups. In order to propose a simplified laboratory test, a comprehensive literary review of the fundamentals of load transfer at joints is made, and the load transfer efficiency obtained via a reduced...

Failure characteristics of reinforced concrete circular slabs subsequently subjected to fire exposure and static load: An experimental study

This study investigated the effect of fire on the ultimate load-bearing capacity of reinforced concrete (RC) slabs. The structural response of RC circular specimens subjected to static load conditions after exposure to a hydrocarbon fire on one side of the specimen was examined. Two fire exposure times were considered (60 and 120 min) in...

Mechanical characterisation of wall tie connection in cavity walls

The assessment of the seismic response of unreinforced masonry (URM) buildings has been a popular topic all over the world in the last decades. In recent years, induced seismicity in the north of the Netherlands increased considerably and introduced seismic risk also in this country. The built environment in the region is mainly composed by...

The static strenght of mechanically fastened carbon-epoxy joints without bending

The mechanical behaviour of mechanically fastened double lap carbon-epoxy joints has been investigated both by experiments (static tests) and by analysis. Several fastener types and joint geometries has been investigated. In the experimental programme the Fibredux 6376/T400H material was used. Two methods to analyze mechanically fastened...

Testing of spacecraft attitude and orbit control systems

The testing of Spacecraft Attitude and Orbit Control Subsystems is described from the early design up to in-flight, inclusive. Main topics dealt with are: description of three generic AOCS test classes, model philosophy, standardization, subsystem static test methods, subsystem dynamic test methods, generic test equipment and test facilities....
