Indirect Determination of Soil Young’s Modulus in Lithuania Using Cone Penetration Test Data

The Baltic Journal of Road and Bridge Engineering, 2022
Simplified methods based on cone penetration test results are commonly used to determine soil deformation modulus, depending on the engineering geological and geotechnical conditions and the complexity of the computational approach.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Influence of Periodic Freezing on the Value of the Elastic Modulus of Light-weight Fibre Concrete

, 2009
This paper deals with the influence of periodic freezing on light-weight concrete characteristics. Three differential sets of light-weight concrete specimens were periodically freezing and non-destructively testing during this time.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

A dynamic damage constitutive model considering the effect of joint inclination on the modulus of elasticity of slates

Scientific Reports
The dynamic damage constitutive model has limitations and needs to reflect the quantitative relationship between the elastic modulus and joint inclination angle of the slate.

Construction of bounds on the effective shear modulus of isotropic multicomponent materials

Vietnam Journal of Mechanics, 2013
In our previous paper, we constructed bounds on the effective bulk modulus of isotropic multicomponent composites using minimum energy principles and modified Hashin-Shtrikman polarization trial fields. In this paper, following the variational approach,

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
