In vivo measurement of regional corneal tangent modulus. [PDF]
Sci Rep, 2017 AbstractCurrently available clinical devices are unable to measure corneal biomechanics other than at the central region. Corneal stiffness (S), thickness, and radius of curvature was measured at the central cornea (primary fixation) and 3 mm from the temporal limbus (primary and nasal fixations).

A novel corneal indentation device for comparison of corneal tangent modulus before and after FS-LASIK in vivo [PDF]
BioMedical Engineering OnLineBackground Corneal refractive laser surgery is widely used to correct myopia and astigmatism due to its safety and effectiveness. However, postoperative changes in corneal biomechanics, such as corneal ectasia, can occur, necessitating a deeper ...

Influence of Prestraining on Tangent Modulus of Tubular Struts [PDF]
Fanāvarī-i āmūzish, 2006 Strain reversal in the inelastic range may cause a dramatic drop in the tangent modulus for mild steel struts. Other material properties also affect the tangent modulus.

p-y curve method based on tangent modulus
Yantu gongcheng xuebao, 2021 It is still a hot problem to calculate the force of laterally loaded piles in engineering. At present, the p-y curve method is mostly adopted in international engineering specifications. Generally speaking, soft soil is different from sandy soil.

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