Concavities on the zonal slowness sectio
✍ V.I. Alshits; P. Chadwick 📂 Article 📅 1997 🏛 Elsevier Science 🌐 English ⚖ 799 KB

The section of the slowness surface of a transversely isotropic elastic material in a zonal plane consists of an ellipse and a quartic curve with two nested branches, the inner of which is convex. Concavities can therefore occur only on the outer branch S and five possibilities arise: (I) S is conve
