Constrained Amorphous Interphase in Poly(l‑lactic acid): Estimation of the Tensile Elastic Modulus [PDF]

open access: yesACS Omega, 2020
The mechanical properties of semicrystalline PLLA containing exclusively α'- or α-crystals have been investigated. The connection between experimental elastic moduli and phase composition has been analyzed as a function of the polymorphic crystalline form.

On the use of constrained modulus for soil settlement analysis

open access: yesMagazine of Civil Engineering
Soil settlement is a key parameter in engineering design of geotechnical structures. Two approaches have been used for the characterization of soil behaviour under one dimensional compression: the linear - nonlinear, the traditional approach, and the ...

Constant modulus constrained codebook synthesis for mmWave full-duplex ISAC devices

open access: yesEURASIP Journal on Wireless Communications and Networking
Self-interference (SI) is a major obstacle to the practical realization of fully full-duplex (FD) systems. This challenge becomes even more critical in FD integrated sensing and communication (ISAC) devices where the sensing signal is of several orders ...

Evaluation of the Organic Soil Compressibility from In-Situ and Laboratory Tests for Road Application

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2021
Organic soil is characterised by high compressibility and should be improved so that it can be used for construction. The use of every method of soil improvement requires knowledge of the compressibility parameters.

Determination of Constrained Modulus of Granular Soil from In Situ Tests—Part 1 Analyses

open access: yesGeotechnics, 2023
Assessing the constrained modulus is a critical step in calculating settlements in granular soils. This paper describes a novel concept of how the constrained modulus can be derived from seismic tests. The advantages and limitations of seismic laboratory

Analysis of Using the Empirical Model of Organic Soil Consolidation to Predict Settlement

open access: yesArchitecture, Civil Engineering, Environment, 2023
The paper describes two models for determining the constrained elasticity modulus of organic soils based on the settlement of an overloading embankment. In these methods, based on the settlement of the embankment of the load exerted on the subsoil, using
