Neurovascular injury is often observed in traumatic brain (TBI). However, the relationship between mechanical forces and vascular still unclear. A key question whether complex anatomy of vasculature plays a role increasing cerebral vessels producing damage. We developed high-fidelity multiscale finite element model rat featuring detailed definition angioarchitecture. Controlled cortical impacts were performed experimentally in-silico. The was able to predict pattern blood-brain barrier found...
Neck protective devices for motorcyclists have been introduced fairly recently but there is no standard method to evaluate their performance. The goal of this study compare the response riders' necks direct impacts on helmet with and without such a device. We investigate three common types cervical injury mechanisms i.e. hyperflexion, hyperextension lateral bending using finite-element method. rotational movement head respect torso, neck shearing axial loads stress distribution throughout...
Robotic patients show great potential for helping to improve medical palpation training, as they can provide feedback that cannot be obtained in a real patient. They information about internal organ deformation significantly enhance training by giving trainees visual insight based on the pressure apply palpation. This achieved using computational models of abdomen mechanics. However, such are computationally expensive, and thus unable real-time predictions. In this work, we proposed an...
Maintaining offshore steel structures is challenging and not environmentally friendly due to the frequent visits for inspection repairs. Some lighthouses are equipped with carbon helidecks fixed onto their lantern galleries in 1970s provide easy safe access maintenance staff inspectors. Even though supporting have maintained integrity still functional harsh environmental conditions, remains a challenge need of which requires flying location lighthouse bring equipment. We developed...
Identification of the constants material models is always a concern. In present work, combined experimental, numerical and optimization technique employed to determine Zerilli-Armstrong model. The experiments are conducted on compressive Hopkinson bar, simulations performed using finite element method carried out genetic algorithm. adopted here, there no need for experimental stress-strain curve which accompanied by restricting phenomenon such as necking in tension bulging compression....
Material models are essential requirements in numerical simulation of mechanical behavior materials particular at high strain rates and elevated temperatures. The involve a number constants to be determined normally by experiment. In this investigation combined experimental, optimization technique is employed obtain the Johnson-Cook model tension. experiments conducted on rate tensile testing apparatus called Flying Wedge. also simulated using finite element method. same specimen geometries...
