Abstract In times of increasing global warming, the awareness necessity for significant CO 2 reduction is growing. Especially in transport and aerospace sector, lightweight construction has potential to achieve emission goals by reducing overall vehicle weight. Thereby, adding fibre-reinforced composites materials such as steel aluminium used weight savings. Furthermore, continuous-fibre-reinfo...

in present paper, a point to point optimal path is planned for a mobile manipulator with flexible links and joints. for this purpose, a perfect dynamic modeling is performed for mobile manipulators considering large deformation in links, shear effects, elastic joints, effect of gravitation, and non-holonomic constraints. to study large deformation of links, non-linear relation of displacement-s...

In nature and engineering applications, wall-bounded flow often encounter a heterogeneous surface condition, such as the atmosphere boundary layer at urban over riveted aircraft surfaces. particular scenario, when heterogeneity is predominantly in spanwise direction of flow, this roughness can generate secondary cross plane which very different from smooth-wall or homogeneous rough-wall layers.

Abstract T‐stubs and L‐stubs loaded in tension are generally assumed contact with a rigid foundation. The prying force stiffness of these components depend on this hypothesis. For double web angle riveted connections, the rests deformable beam/column web. objective present paper is to take into account effects deformability development area, rivet forces tensile stiffness. An enhanced theory be...

failure in timber structures occurs mainly in crucial points such as joints areas. therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. this research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of gfrp sheets. a singl...
