Glossary G The terms defined here are those that will be seen in the books posted on the website. It is not a complete compendium of all mechanics terms. Term Definition Airy stress function A function that satisfies stress equilibrium equations in two dimension and whose second deriva- tives give the stresses. Anisotropic material A material that has a stress-strain relationships that changes with orientation of the coordinate sys- tem at a point. Axial displacement Displacement caused by axial forces. Axial force Normal force acting on a surface in the direction of the axis of the body. Axial force diagram A plot of the internal axial force versus x. Axial member A long straight body on which the forces are applied along the longitudinal axis. Axial rigidity The product of modulus of elasticity and cross-sectional area. Axial strain energy Energy stored during axial deformation Axial stress The normal stress acting in the direction of the axis of a slender member.

Axial rigidity The product of modulus of elasticity and cross-sectional area. Students can study the cartridge loops at will on recommendation of the instructor, or they may be assigned as homework.

For this event we are soliciting movies that display research in the New England community in any field suitable to be considered for NEW. As we describe in detail later there is an award for the best entries. Movies have become an integral part of the arsenal of instruments used to communicate scientific research. An ever growing number of forums including conference events and supplementary information sections of scientific publications are incorporating movies in their dissemination formats. Undoubtedly, movies will be playing a much greater role in the scientific communication and we bring to the New England mechanics community a glimpse of the future. The submitted movies will pass through a moderation round for assuring adherence to the above rules and suitability for NEW. Mech forum.

Enneper Surface Enneper Surface. Supplementary Movie 4 27M, avi. Maximum octahedral shear stress theory A material will fail when the maximum octahedral shear stress exceeds the octahedral shear stress at the yield obtained from a uniaxial tensile test. Science, , Axial strain energy Energy stored during axial deformation Axial stress The normal stress acting in the direction of the axis of a slender member. Supplementary information is available for this paper at Merkel C, et al. Also called Youngs modulus. Maxwell model A model used in obtaining viscoelastic material constants in which a dashpot and spring are used in series. Solids, 60, Direct observation is required to disambiguate the mechanism of nanomechanical deformation of nacre; however, most knowledge of the biomineral toughening process is assembled from microscale tribology 8 , 12 , 15 , 16 , tensile 5 , 12 , 15 , 19 , 20 , 22 , 39 , or compression 14 , 19 , 40 testing on bulk specimens.

A natural composite material, nacre is reported to consist of roughly 95—98 wt. Shearing stresses are commonly found in bolts, pins, and rivets used to connect various structural members and machine components 1 - Mineral bridges in nacre. In-Class Activity. Isotropic material A material that has a stress-strain relationships independent of the orientation of the coordinate sys- tem at a point. Collapse moment Moment at which the structure collapses. They are ideal for illustrating a point that arises during the course of a lecture. In the intervening years both these speculations have become resounding positive statements. Advanced Search.
