Effect of rock loading rate based on crack extension and propagation

open access: yesScientific Reports, 2022
When subjected to constant static load, after a period of damage accumulation and crack development, the rock will fail under a load lower than its compressive strength.

Rate-dependent tensile behavior and statistic strength model for fiber tow composites

open access: yesPolymer Testing, 2023
The mechanical performance of the fiber tow composite is crucial for textile composites. To characterize the tensile properties of the carbon fiber tow composite, a tensile test methodology for high strain rate loading was developed based on the Split ...

Fatigue limit assessment by energetic analyses in static and cyclic tensile tests

open access: yesProcedia Structural Integrity, 2019
Abstract Inside a research program agreed with the AIAS-MEAS Energy Methods Group, this preliminary study starts defining the fatigue parameters of a commercial steel in static and cyclic loading conditions. The final purpose of the research is to define the fatigue limits in different loading conditions using different energetic methodologies and ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Load Ratio Effect on Fracture Resistance Curve of SA312 TP304 under Reverse Cyclic Loading Condition [PDF]

open access: yes한국정밀공학회지, 2017
Seismic load induces a reverse cyclic load that alternately applies a tensile and a compressive load to a structure. For nuclear piping material, safety is assessed in terms of fracture toughness.

Validating performance of automotive materials at high strain rate for improved crash design [PDF]

open access: yes, 2006
This paper investigates sources of performance variability in high velocity testing of automotive crash structures. Sources of variability, or so called noise factors, present in a testing environment, arise from uncertainty in structural properties ...

Stress-strain synchronization for high strain rate tests on brittle composites [PDF]

open access: yes, 2018
Nowadays, many researchers develop rate-dependent composite material models for application in dynamic simulations. Ideally, full stress-strain curves at a wide range of strain rates are available for identification of the different parameters of these ...

Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Static strength tests and effects of defects on dovetail elements of ceramic matrix composites turbine rotor blades

open access: yesJournal of Aeronautical Materials
The dovetail of ceramic matrix composites(CMC)turbine blade is the key to the assembly and ability to withstand centrifugal loads of the blade. In order to study the mechanical behaviour of the blade dovetail prepared by the melt infiltration(MI)method ...

Micromechanism of Damage of the Graphite Spheroid in the Nodular Cast Iron During Static Tensile Test

open access: yesJournal of Manufacturing and Materials Processing, 2020
This work was focused on two particular phenomena contributing to a damage process of nodular cast iron under tensile stress: Internal destruction of graphite nodule and debonding at graphite/matrix (G-M) interface.
