| dc.description | Una metodología sencilla para modelar bandas de corte tan fuertes discontinuidades de desplazamiento en un método meshfree adaptativa se presenta. La banda de cizallamiento está representado por un salto de desplazamiento en las posiciones de partículas discretas. El salto desplazamiento en dirección normal se suprime con el método de penalti. La pérdida de la estabilidad del material se utiliza como criterio de transición de continuo a discontinuo. El método es de dos y tres dimensiones. Ejemplos de bandas de cizallamiento incluyendo complicada transición de fracaso-frágil-dúctil a se estudian y se compararon con datos experimentales y otros ejemplos de la literatura. | es_ES |
| dc.description.abstract | A simple methodology to model shear bands as strong displacement discontinuities in an adaptive meshfree method is presented. The shear band is represented by a displacement jump at discrete particle positions. The displacement jump in normal direction is suppressed with penalty method. Loss of material stability is used as transition criterion from continuum to discontinuum. The method is twoand three-dimensional. Examples of complicated shear banding including transition from brittle-to-ductile failure are studied and compared to experimental data and other examples from the literature. | es_ES |
