Delamination is one of the most common failure modes in composite structures. In the case of in-plane compressional loading, delamination of a layered flat structure can cause a local buckling in delaminated area which subsequently affects the overall stiffness of the initial structure. This leads to an early failure of the overall structure. Moreover, with an increase in load, the delaminated ...

In this paper, finding the maximum load carrying capacity of mobile manipulators for a given two-end-point task is formulated as an optimal control problem. The solution methods of this problem are broadly classified as indirect and direct. This work is based on the indirect solution which solves the optimization problem explicitly. In fixedbase manipulators, the maximum allowable load is limit...

This paper presents a computational technique for determining the maximum allowable load of wheeled mobile manipulators for a desired trajectory. Full load motion of mobile manipulators while carrying a load is an important consideration in their application and motion planning. The number of factors limits the maximum allowable loads, which can be achieved by a mobile manipulator during a give...

In this paper, an algorithm is proposed to improve the Maximum Load Carrying Capacity (MLCC) of exible robot manipulators. The maximum allowable load which can be achieved by a exible manipulator along a given trajectory is limited by the joints' actuator capacity and the end e ector accuracy constraint. In an open-loop approach, the end e ector deviation from the prede ned path is signi cant a...

the work presented in this paper investigates the causes of size effects in structural-concrete members. it isbased on the use of a finite-element model found to yield realistic predictions of structural-concrete behavior in allcases investigated to date. in fact, the previous use of this model in investigations of size effects in reinforced-concretebeams indicated that such effects reflect the...

Most of the laboratory tests investigated the flexural performance of un-preloaded or undamaged RC beams strengthened with CFRP composites. However, in engineering applications, the structural member must carry a certain load or damage. There is a lack of systematical investigations on the effects of preload or damage level on the flexural load-carrying capacity of CFRP-strengthened RC beams. T...

In this paper a performance analysis is presented for a cable-suspended parallel manipulator. Experimental results from some first tests are presented and discussed to validate the theoretical calculation of load carrying capacity. The loadcarrying capacity during a given trajectory is obtained. This computational technique is tested on a typical planar cable suspended manipulator. The experime...

ABSTRACT: An attempt has been made to study and analyze the performance of a magnetic fluid based squeeze film in a rough porous parallel plate slider bearing. The bearing surfaces are considered to be transversely rough. The random roughness of the bearing surfaces is characterized by a stochastic random variable with non-zero mean, variance and skewness. A magnetic fluid is taken as the lubri...

In this study, the load carrying capacity was evaluated using results of dynamic test, instead static test field, in precision safety diagnosis a high-speed railway PSC BOX girder bridge, and differences impact factor bridge according to condition train configuration were compared. The obtained from measured displacement response via tests for performed on bridges. analysis conditions included ...
