Modeling Damage Evolution and Damage Healing using Data Driven Method
<p>Advanced aircraft use composite materials in over 50% of their airframe structures. Defects in composite materials frequently arise during manufacturing and processing phases, greatly affecting structural integrity and reliability. The intrinsic self-healing polymers are smart materials that …

The Damage Done
Conde, Kelly, M.A., Spring 2013 Journalism The Damage Done Chairperson: Dennis Swibold The water that ran from Helen Ricker’s faucet stank of rotten eggs and of chemicals. It ran orange and greasy. It stained her clothes and clung to her skin. Ricker lives on the Fort Peck Indian Reservation, three …

Damage Control Measures in Composites: Focus on Damage Tolerance of Aerospace Structures
<p>Barely Visible Impact Damage (BVID) in composite materials presents a stealthy yet significant risk to structural integrity, particularly challenging due to its elusive nature. The approach adopted here diverges from traditional methodologies, focusing on the novel application of Digital Image …

Compensation for Vaccine Damage
… the law in England and Wales relating to vaccine damage is in need of reform. The answer to this question is determined by a moral and legal analysis of current vaccination policy and practice. The existing literature consists primarily of medical papers discussing the possibility of vaccine …

Post-Earthquake Damage Repair and Probabilistic Damage Control Approach for Reinforced Concrete Bridges
… reinforced polymers (CFRP) and probabilistic damage control approach (PDCA) for reinforced concrete (RC) bridges. To develop repair methods, first repair objectives were defined. To define repair objectives, internal earthquake damage was quantified and correlated to a series of visible damage …

Phased Array Damage Detection and Damage Classification in Guided Wave Structural Health Monitoring
… and approaches in SHM have been developed for damage detection, diagnosis, and prognosis. Among the methods developed, the guided Lamb wave based SHM can be a promising technique for damage evaluation since it provides reliable damage information through signals propagating over large distance …

A method to estimate wind turbine blade damage and to design damage resilient blades
… Each type of particle was associated with a damage mode, which depends on the mass, size, and hardness of the particle. It was found that insects strike and adhere to the blade in a region close to the leading edge. On the other hand, it was seen that sand grains promote erosion just …

Cerebral damage associated with alcoholism
… tests selectively sensitive to damage in circumscribed brain areas-~~~ The performance of a group of male alcoholics (N=15) with a self-reporte?- drinking history less than ten years, and a group of male alcoholics (N=15) with a self-reported drinking history of ten or more years …

Microvascular strategies for damage restoration
… for mass transport of liquid healing agents to damage regions that intersect the vasculature. Microvascular self-healing has proven effective in restoring fracture toughness and modulus by re-bonding the surfaces of damage-induced microcracks; however, large damage volumes (crack separations > …

Ion Implantation Damage in Semiconductors
The diffuse X-ray scattering from defects in ion implanted Si was studied at implantation temperatures ranging from 100 K to 300 K, and the results were compared to simulations of the scattering intensity from realistic defects in Si. In situ studies of keV implants identified close Frenkel pair …

Ion Implantation Damage in Solids
Ion induced surface smoothing and roughening processes were studied using Molecular Dynamics (MD) computer simulation. The simulations on self-ion bombarded W showed the effect of the surface on defect production and the roughening of the surface. The simulations on the CuTi, Ag and Ni with …

Damage identification using inductive learning
A damage identification method incorporating the use of inductive learning is presented. Inductive learning is the process of learning from examples. The method utilizes as much dynamic-response data as is available, ordering this information to find the best data with which to discriminate among a …

Seismic Damage Analysis and Damage-Limiting Design for R/c Structures (Earthquake, Building, Reliability, Design)
A model for evaluating structural damage in reinforced concrete structures under earthquake ground motions is proposed. Damage is expressed as a linear combination of the maximum deformation and the effect of repeated cyclic loadings. Available static (monotonic) and dynamic (cyclic) test data were …

Modeling of active crack damage control and the active fatigue damage control of adhesive joint
Active damage control is a new technique which mimics the self-repairing capability of biological beings and can be used to greatly increase the structural integrity and fatigue life. This thesis describes two approaches used in active damage control: direct stress cancellation and indirect stress …

Damage and repair identification in reinforced concrete beams modelled with various damage scenarios using vibration data
… aims at developing a novel vibration-based damage identification technique that can efficiently be applied to real-time large data for detection, classification, localisation and quantification of the potential structural damage.

UHRF1 and the DNA Damage Response
… this threat, collectively referred to as the DNA damage response. Cells that lose the ability to cope with DNA damage risk the acquisition of deleterious changes to DNA sequence or structure. I initially set out to identify and characterize candidate proteins that interact with Mus81-Eme1, an …

Structural damage detection using ambient vibrations
… ambient random vibration response to detect damage level and location. The use of ambient vibration is advantageous because excitation is caused by service conditions such as normal vehicle traffic on a highway bridge, train passage on a railroad bridge, or wind loads on a tall building. This …
