Thresholds for thermal damage to normal tissues: An update [PDF]

open access: yesInternational Journal of Hyperthermia, 2011
The purpose of this review is to summarise a literature survey on thermal thresholds for tissue damage. This review covers published literature for the consecutive years from 2002-2009. The first review on this subject was published in 2003. It included an extensive discussion of how to use thermal dosimetric principles to normalise all time ...

Thermal damage to red cells [PDF]

open access: yesJournal of Clinical Pathology, 1970
Erythrocytes from a burned patient show a temporal sequence of morphological changes. Immediate severe changes occur which are followed by a transient phase only of less abnormal morphology. Heating whole blood in vitro to 49°C instead of 50°C does not show the expected dose response curve.

Thermal Damage to Chloroplast Envelope Membranes [PDF]

open access: yesPlant Physiology, 1989
Nuclear magnetic resonance was used to detect thermal injury to chloroplasts in vivo. A lesion occurs in the chloroplast envelope membrane at temperatures between 53 degrees C and 57 degrees C, depending on species, leaf condition, and heating rate. The injury is associated with a sudden loss of water from the chloroplast.

Prediction of tissue thermal damage

open access: yesTechnology and Health Care, 2016
This paper presents a method to characterize tissue thermal damage by taking into account the thermal-mechanical effect of soft tissues for thermal ablation. This method integrates the bio-heating conduction and non-rigid motion dynamics to describe thermal-mechanical behaviors of soft tissues and further extends the traditional tissue damage model to ...

Analysis of Thermal Damage in FRP Drilling

open access: yesProcedia Engineering, 2016
Abstract Among machining operations applied to polymeric composite materials, drilling is the more important one due to the need to implement mechanical couplings, which in most cases are not yet possible using structural adhesives. Such process is very critical because not only it causes the interruption of the fibers continuity, but also it can ...

Evaluation of Thermal Damage in a Pig Model

open access: yesJournal of Investigative Surgery, 2012
Electrosurgical vessel sealing produces seals that can withstand intraluminal pressures well above the physiological range. In many cases it is more efficient than other methods, such as sutures, hemoclips, and ultrasonic coagulation devices, but bears lateral thermal damage as a side effect.

Thermal damage in crystalline rocks: the role of heterogeneity

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Abstract Accurately evaluating the impact of microstructural heterogeneity on thermal damage and failure mechanisms in crystalline rocks is crucial for geothermal energy development and the establishment of nuclear waste repositories. However, in thermal damage analyses of crystalline rocks using the discrete element method, most studies fail to ...

CFRP Fatigue Damage Detection by Thermal Methods

open access: yesMaterials, 2022
In this work, the fatigue damage of CFRP uniaxial composite specimens were studied using thermal methods to determine the fatigue behavior. The aim was to evaluate the fatigue damage as a function of the number of cycles. Consequently, the damage process was studied in terms of a global indicator, considering the stiffness decay, and in terms of local ...

Damage processes in thermoviscoelastic materials with damage‐dependent thermal expansion coefficients [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2015
In this paper, we prove existence of global in time weak solutions for a highly nonlinear PDE system arising in the context of damage phenomena in thermoviscoelastic materials. The main novelty of the present contribution with respect to the ones already present in the literature consists in the possibility of taking into account a damage‐dependent ...

Thermal Cycling Damage and Thermal Barrier Property of TBC.

open access: yesQUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1998
Two kinds of thermal cycle tests with short (10 min) and long (23h) holding times were carried out to investigate thermal cycling damage characteristics and thermal barrier property of thermal barrier coatings (TBCs). Surface cracks vertical to the coating surface were nucleated due to thermal stress during both the thermal cycle tests.
