Confined excitons under biaxial compression and tension
Surface Science, 1990The properties of confined excitons have been investigated under both biaxial compression and tension, which result upon cooling from the different thermal expansion coefficients of a thin GaAs/AlGaAs multiple quantum well (MQW) sample and various sample holders.

Capillary-Induced Wrinkle-to-Fold Transitions Under Biaxial Compression
Langmuir, 2021Wrinkles in bilayer systems comprising a thin stiff film attached to a soft substrate can globally transition into folds under sufficiently large compression. This phenomenon has been extensively studied primarily using uniaxially compressed systems. However, inducing the wrinkle-to-fold transition at designated locations on a wrinkled surface under ...

Analysis of granule fracture under biaxial compression
Ceramics International, 2017Abstract In this study, the mechanism of granule fracture under biaxial compression was investigated through both experimental and simulation methods. The results of the experiment indicate that the fracture behavior differs depending on the number of compressional axes.

Behavior of Concrete in Biaxial Compression
Journal of the Structural Division, 1967The behavior of concrete in biaxial compression is briefly described as determined from experiments performed on six mixes by a testing machine capable of loading concrete slabs simultaneously in two orthogonal directions. Strain readings in the three principal directions, microcracking, and ultimate load were observed and measured for various values ...

Strength of porcelain with biaxial compression
Strength of Materials, 19841. Strength determined in the fourth quadrant of the coordinate plane for porcelain is 60–70% greater than the level of average failure stresses with loading along two axes by smooth metal supports, depending on the principal stress ratio, and with σ2/σ3=0.25 it reaches a maximum value of 1020 MPa which is 5 and 25% greater than the ultimate ...

Slender RC Compressed Members in Biaxial Bending
Journal of the Structural Division, 1977A method is presented for the “exact” nonlinear analysis of reinforced and prestressed concrete slender members subject to biaxial bending. The main feature of the method is the procedure that analyzes the stress-strain state of sections, under given axial force and biaxial moment.

Magnetophotoluminescence of biaxially compressed InAsSb quantum wells
Applied Physics Letters, 1995Heterostructures with biaxially compressed InAsSb are being considered as active regions for midwave infrared diode lasers. Quantum wells of biaxially compressed InAs1−xSbx (x≊0.09) in unstrained InAs were characterized using magnetophotoluminescence. The quantum size shift of the photoluminescence for a series of quantum wells produced an estimate of ...

Materials and Structures, 2008
To meet the requirement of nonlinear analysis and design for mass concrete structures, the mechanical characteristics of mass concrete specimens 25 × 25 × 40 cm with three-graded aggregate 5–80 mm under biaxial compression-tension and triaxial compression-compression-tension was studied experimentally with the multiaxial concrete apparatus.

Hierarchical folding of elastic membranes under biaxial compressive stress
Nature Materials, 2011Mechanical instabilities that cause periodic wrinkling during compression of layered materials find applications in stretchable electronics and microfabrication, but can also limit an application's performance owing to delamination or cracking under loading and surface inhomogeneities during swelling.

The dynamics of interacting folds under biaxial compressive stresses
Soft Matter, 2016The gradual in-plane compression of a solid film bonded to a soft substrate can lead to surface wrinkling and even to the formation of a network of folds for sufficiently high strain. An understanding of how these folds initiate, propagate, and interact with each other is still lacking.
