In general, the yield strength of a material is an adequate indicator of the material's mechanical strength. Considered in tandem with the fact that the yield strength is the parameter that predicts plastic deformation in the material, one can make informed decisions on how to increase the strength of a material depending on its microstructural ...
The characterization of mechanical properties in polymers typically refers to a measure of the strength, elasticity, viscoelasticity, and anisotropy of a polymeric material. The mechanical properties of a polymer are strongly dependent upon the Van der Waals interactions of the polymer chains, and the ability of the chains to elongate and align ...

Solid mechanics (also known as mechanics of solids) is the branch of continuum mechanics that studies the behavior of solid materials, especially their motion and deformation under the action of forces, temperature changes, phase changes, and other external or internal agents.
Alternative material models have been proposed to simulate ratcheting, such as Chaboche, Ohno-Wang, Armstrong–Frederick, etc. [6] Ratcheting is a significant effect to be considered to check permanent deformation in systems which undergoes a cyclic loading.
Fracture mechanics is a fundamental discipline for understanding the mechanical behavior of materials, particularly in the presence of cracks. The critical parameter in fracture mechanics is the stress intensity factor (K), which is related to the strain energy release rate (G) and the fracture toughness (G c). When the stress intensity factor ...
In certain situations, not commonly considered in the analysis of the mechanical behavior of materials, it becomes necessary to include two other types of forces: these are couple stresses [note 1] [note 2] (surface couples, [11] contact torques) [12] and body moments. Couple stresses are moments per unit area applied on a surface.
It is the "letters" section of Acta Materialia and covers novel properties, or substantially improved properties of materials. Specific materials discussed are metals, ceramics and semiconductors at all length scales, and published research endeavors explore the functional or mechanical behavior of these materials. Articles tend to focus on the ...
