In this work, we applied a finite element model to predict the cyclic lifetime of 4130 steel cylinders under the influence of hydrogen. This example is used to demonstrate the efficacy of a fatigue crack growth (FCG) model we have developed. The model was

In this work we further develop a model to predict hydrogen-assisted fatigue crack growth in steel pipelines and pressure vessels. This implementation of the model is informed by finite element code, which uses an elastic-plastic constitutive model in

Numerical models based on cohesive zones are usually used to model and simulate the mechanical behavior of laminated carbon fiber reinforced polymers (CFRP) in automotive and aerospace applications. The codes of these models require different interlaminar

Although they are amongst the most efficient engine types, compression-ignition engines have difficulties achieving acceptable particulate emission and NOx formation. Indeed, catalytic after-treatment of diesel exhaust has become common and current efforts
We describe preliminary models for the viscosity, thermal conductivity, and surface tension for pure fluids that are constituents of four surrogate fuels for ultralow-sulfur diesel fuels developed under the auspices of the Coordinating Research Council
This survey provides a literature review of docking research, an area that has relatively few research articles as compared to generic automatic guided vehicle (AGV) or mobile robot research. Docking refers to the arrival and act of a vehicle stopping at a

Mobile manipulators can be effective, efficient and flexible for automation on the factory floor but will need safety and performance standards for wide adoption. This paper looks at a specific area of performance standards [1] for docking and workpiece
Microbiologically influenced corrosion (MIC) of carbon steel infrastructure is an emerging cost issue for the ethanol fuel industry. One bacterial species found in ethanol fuel environments, Acetobacter aceti, can convert ethanol to the corrosive species

Mobile manipulator performance measurement research is relatively minimal as compared to that of robot arms. Measurement methods, such as optical tracking systems, are useful for measuring the performances of mobile manipulators, although at a much higher

This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles, as com-pared to other mobile manipulator research areas. The survey begins with a
A workshop was held at the IEEE International Conference on Robotics and Automation, called: "Autonomous Industrial Vehicles: From the Laboratory to the Factory Floor." Nine research papers were presented followed by a discussion session summarized in this
Automated Guided Vehicles (AGV's) have typically used for industrial material handling since the 1950's. Since then, US and European safety standards have evolved to protect nearby workers. However, no performance standards have been developed for these
Performance standards for industrial mobile robots and mobile manipulators (robot arms onboard mobile robots) have only recently begun development. Low cost and standardized measurement techniques are needed to characterize system performance, compare

Ubiquitous, commercial deployment of automated road vehicles is desirable in order to realize their potential benefits such as crash avoidance, congestion mitigation, reduced environment impact, reduced driver stress, and increased driver productivity. A
The development of surrogate fuels with measured and predicted thermophysical properties similar to their authentic refinery stream counterparts is critical for the development of fuels from alternative feed-stocks and the optimization of engines to

Manufacturing robotics are moving towards human-robot collaboration with light duty robots being used side-by-side with workers. Similarly, exoskeletons that are both passive (spring and counterbalance forces) and active (motor forces) are worn by humans

The primary objectives of this work were to formulate, blend, and characterize a set of four ultra-low-sulfur diesel surrogate fuels in quantities sufficient to enable their study in single-cylinder engines and combustion-vessel experiments. The surrogate

Surface-active trace compounds present in diesel fuels protect pumps and injectors against premature wear through boundary lubrication. Due to the vast number of hydrocarbon compounds found in petroleum distillate fuels, it is difficult to measure the
