Estimation of the Fracture Probability Parameters for Specimens Made by JIS SM490A Steel

Materials Research, 2021
This work established the fracture probability equation for JIS SM490A steel using the computational model supported by the local approach and the standard Crack Tip Opening Displacement (CTOD) fracture toughness experiments.

A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 10, Page 152-158, October 2025.
ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.

An Experimental Study of Fracture Parameters of Concrete Produced With Basalt Aggregate by Peak‐Load Method

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Limestone or river aggregates have been traditionally used as aggregates in ready‐mixed concrete from the past to the present. The depletion of these natural aggregates used in ready‐mixed concrete has led the concrete industry to investigate aggregate resources and search for alternative aggregates.

Determination of dynamic fracture toughness using a new experimental technique

EPJ Web of Conferences, 2015
In other studies dynamic fracture toughness has been measured using Charpy impact and modified Hopkinson Bar techniques. In this paper results will be shown for the measurement of fracture toughness using a new test geometry.

On comparison of fracture energy measured for six hot mix asphalt composite mixtures using force–load line displacement and force–crack mouth opening displacement curves at intermediate temperatures and different loading rates

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 10, Page 3858-3873, October 2024.
Abstract There are two methods for determining the fracture energy (Gf) of hot mix asphalt (HMA) composites at intermediate temperatures: (i) load–crack mouth opening displacement (CMOD) and (ii) load–load line displacement (LLD) curves. The effects of these two methods on the Gf values of different HMA mixtures are investigated at different loading ...

Preliminary Evaluation of the Influence of Hydrogen on the Fracture Toughness of an X65 Gas‐Transmission Pipeline Steel

Advanced Engineering Materials, Volume 26, Issue 16, August 2024.
We measured two values of fracture toughness for X65 steel in air (KQ of 369 and 487 MPa√m$\sqrt{} \text{m}$) and two essentially American Society for Testing of Materials–valid values of fracture toughness of KJ1C of 150 and 189 MPa√m$\sqrt{} \text{m}$ for X65 subjected to in situ hydrogen charging thought to be equivalent to a hydrogen gas pressure ...

Effect of CNT filler and temperature on fracture toughness of epoxy composites reinforced with carbon fabric

Engineering Reports, Volume 6, Issue 8, August 2024.
In present research the fracture behavior of carbon fabric‐epoxy composites was evaluated with the addition of 0.1, 0.2, 0.5, and 0.75 weight percentages of carbon nano tubes at different temperatures. Abstract In present research the fracture behavior of carbon fabric‐epoxy composites (CE composites) was evaluated with the addition of 0.1, 0.2, 0.5 ...
