Impact Resistance of Composite Structures
A new approach based concepts of the Discrete Element Method, is presented for impact resistance analysis of composites. The method is capable of analysing the progressive fracturing and fragmentation behaviour as well as potential post cracking interactions caused by the newly created crack sides and segments. The imminence of a material crack is monitored by an anisotropic Hoffman model . To ...
متن کاملDeformation Characteristics of Composite Structures
The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

متن کاملExperimental Study on the Fire Resistance Performance of Prestressed Composite Beam with Corrugated Web under Standard Fire with Loading Condition
In this study, fire resistance tests were performed on a conventional slim floor beam and a prestressed composite beam with corrugated webs, which is suitable for a long-span structure with a reduction in story height by utilizing the prestress and accordion effect. In the fire test program, the ISO 834 standard fire curve was adopted. Key test variables were the effect of prestress, shape of c...
متن کاملThermal Conductivity and Fire Resistance of Borassus Seed Shoot Fiber Reinforced Composite
The natural fiber reinforced composites have the advantage of being light weight, renewable, bio-degradable, cheap and eco-friendly. So there is every need to investigate potentiality of natural fibers and its composites, which can be used in highly demanding situations. However, very small contribution of research work exists in the design and fabrication of composite materials using natural f...
