Design and Development of an Accessible Clip Gauge Extensometer for CMOD Measurement in Fracture Mechanics

Engineering Reports, Volume 8, Issue 2, February 2026.
A low‐cost clip gauge extensometer for crack mouth opening displacement was developed from accessible procedures and materials. Accuracy and repeatability comparable to commercial devices were demonstrated in calibration and fracture tests, enabling reliable measurement in CT specimens for resource‐constrained laboratories.

On the Identification of Dissipative Phenomena in Fatigue‐Loaded 2024 Aluminum by Means of Second Harmonic of Temperature Analysis

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 10, Page 4105-4118, October 2025.
ABSTRACT This study explores the use of temperature harmonics to detect intrinsic dissipation during cyclic loading in aluminum alloys. Under sinusoidal loading, the temperature of a solid is modulated by thermomechanical heat sources. The primary source is the thermoelastic effect, which modulates the temperature at the load frequency and twice the ...

Effects of Ion Irradiation on Stage II Fatigue Crack Growth and Plasticity

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 4, Page 1219-1229, April 2024.
Abstract Fatigue crack growth characteristics of ion irradiated compact tension (CT) specimens were evaluated in the Paris law region. Fatigue crack growth was monitored under tension‐tension loading and the thermoelastic response was measured. Two stages of crack propagation were identified.

Fatigue limit estimation of metals based on the thermographic methods: A comprehensive review

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 3, Page 611-646, March 2024.
Abstract Infrared thermography has been under review in the last 30 years due to its versatility and potential in the detection of the thermal signature associated with intrinsic energy phenomena due to dissipative processes, specifically those relying on mechanical fatigue.

Effect of Using a Visible Camera in a Remote Crack Detection System Using Infrared Thermography on an Actual Bridge

Proceedings
The time change in data measured by infrared thermography is used to analyze thermoelastic stress. Displacement caused by the load on the measurement object is the cause of the apparent temperature change.

Full-Field Imaging for Evaluating Mode-II Fracture Toughness in CFRP Laminates

Proceedings
To replicate delaminations at the coupon and substructural scales, simulated defects are often introduced into test specimens; therefore, understanding their behaviour within the laminate is essential.
