Topological design of microstructures of cellular materials for maximum bulk or shear modulus

Computational Materials Science, 2011
This paper presents a new approach to designing periodic microstructures of cellular materials. The method is based on the bidirectional evolutionary structural optimization (BESO) technique. The optimization problem is formulated as finding a micro-structural topology with the maximum bulk or shear modulus under a prescribed volume constraint.

Effect of consolidation ratios on maximum dynamic shear modulus of sands

Earthquake Engineering and Engineering Vibration, 2005
The dynamic shear modulus (DSM) is the most basic soil parameter in earthquake or other dynamic loading conditions and can be obtained through testing in the field or in the laboratory. The effect of consolidation ratios of the maximum DSM for two types of sand is investigated by using resonant column tests.

Maximum shear modulus anisotropy of rooted soils [PDF]

Géotechnique
The maximum shear modulus (G0(ij)) of rooted soils is crucial for assessing the deformation and liquefaction potential of vegetated infrastructures under seismic loading conditions. However, no data or theory are available to account for the anisotropy of G0(ij) of rooted soils.

Comparative Study on Laboratory and Field Test of Maximum Dynamic Shear Modulus

Applied Mechanics and Materials, 2012
The dynamic shear modulus (DSM) is the most basic soil parameter in earthquake or other dynamic loading conditions and can be obtained through testing in the laboratory and in the field. The experimental result of maximum DSM by using resonant column devices is compared with the field test data obtained from shear wave velocity measurement in the paper.

A practical method for estimating maximum shear modulus of cemented sands using unconfined compressive strength

Journal of Applied Geophysics, 2017
Abstract The composition of naturally cemented deposits is very complicated; thus, estimating the maximum shear modulus (Gmax, or shear modulus at very small strains) of cemented sands using the previous empirical formulas is very difficult. The purpose of this experimental investigation is to evaluate the effects of particle size and cement type on ...

Field Investigation of Maximum Dynamic Shear Modulus of Clay Deposit Using Seismic Piezocone

International Journal of Civil Engineering, 2018
The maximum dynamic shear modulus (Gmax) of soils is a fundamental parameter used in the evaluation of soil dynamic behavior and seismic design in geotechnical engineering. In this study, seismic piezocone (SCPTU) and resonant column (RCT) test methods were adopted for measuring soil shear wave velocity (Vs) in Jiangsu Province of China.

Evaluation of liquefaction resistance of sand by maximum shear modulus

Journal of the Chinese Institute of Engineers, 1994
Abstract Laboratory tests and in‐situ seismic cone penetration tests are conducted to evaluate the liquefaction resistance of Lanyang sandy soils. Resonant column tests and cyclic torsional shear tests are performed on remolded samples to establish the relationship between the maximum shear modulus and the liquefaction resistance.

Estimating the Maximum Shear Modulus with Neural Networks

2013
Small strain shear modulus is one of the most important geotechnical parameters to characterize soil stiffness. In-situ stiffness of soils and rocks is much higher than was previously thought as finite element analysis have shown. Also, the stress-strain behaviour of those materials is non-linear in most cases with small strain levels.
