Numerical Analysis of Delamination Buckling in Composite Cylindrical Shell under Uniform External Pressure: Cohesive Element Method
Nowadays, due to high ratio of strength to weight, composite cylindrical shells are extensively used in a great variety of different industrial applications and under different cases of loads. In this study, the buckling of composite cylindrical shells was examined under uniform external pressure. The buckling analysis of composite cylindrical shells was first done by using theoretical relation...
متن کاملApplication of the discrete element method to model cohesive materials
One way to include fracture and fragmentation when analyzing loaded mechanical systems is based on the DEM, [2], [3]. In recent years this approach was adopted in geomechanics and civil engineering to model fracture in elastic-brittle materials, e.g. [1] and [5]. Using this approach, the material is considered as being fully discontinuous and made up by assembling and bonding adjacent discrete ...

متن کاملMicromechanical Considerations of Particle Breakage Using Discrete Element Method
Using DEM (Discrete Element Method), a model is presented to simulate the breakage of two-dimensional polygonshaped particles. In this model, shapes of the particles generated after breakage are predefined and each uniform (uncracked) particle is replaced with smaller inter-connected sub-particles. If the bond between these sub-particles breaks, breakage will happen. With the help of this model...
متن کاملA Study of the Wave Propagation Velocity in Granular Soils Using Discrete Element Method (DEM)
In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...
