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.
A solid is a material that can support a substantial amount of shearing force over a given time scale during a natural or industrial process or action. This is what distinguishes solids from fluids, because fluids also support normal forces which are those forces that are directed perpendicular to the material plane across from which they act and normal stress is the normal force per unit area of that material plane. Shearing forces in contrast with normal forces, act parallel rather than perpendicular to the material plane and the shearing force per unit area is called shear stress.

It is most common for analysts in solid mechanics to use linear material models, due to ease of computation. However, real materials often exhibit non-linear behavior. As new materials are used and old ones are pushed to their limits, non-linear material models are becoming more common.
The mechanics of solids is an engineering science that is fundamental to the practice of mechanical, civil, structural, and aeronautical engineering; it is also directly relevant to materials engineering, nanotechnology, biology, geophysics, and other branches of engineering and applied science. The Mechanics of Solids Group at Brown University fosters a balanced program of research and instruction that integrates the perspectives of continuum mechanics, structure of matter, and materials science. The program has a long tradition of leadership through innovations in the analytical, computational, and experimental concepts and methodologies that form the core of the field.
Mechanics of Solids is a peer-reviewed journal. It publishes articles in the general areas of the dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is the vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity, and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with an analysis of contemporary technological problems. Mechanics of Solids publishes English translations of articles from Izvestiya RAN, Mekhanika Tverdogo Tela and other source journals and original unsolicited articles in the English language. The source of each article is described at the article level on the title pages. The final decision about the publication in Mechanics of Solids is made by its editorial board regardless of the source. The editorial and peer review policies are the same for all translated and original articles. The journal is interested in the global cooperation of scientists and has the aim of becoming an international publication. Researchers from around the globe are encouraged to submit their work in English.

Our Mechanics and Materials group includes an interdisciplinary spectrum of research concerned with the study of deformation, fracture, fatigue, and failure of solids at different time and length scales (from atoms to planets) through advanced analytical, computational, and experimental techniques.
Current research directions include but are not limited to: fatigue crack initiation, hydrogen embrittlement, hypervelocity impact, shocks and wave propagation, nanomaterials, constitutive modeling, damage evolution, failure prediction, nonlinear mechanics of solids, thermal barrier coatings, high-strain-rate behavior and dynamic failure processes, deformation and failure mechanisms across multiple scales, growth and remodeling of fibrous soft tissues, planetary impact, asteroid disruption, injury biomechanics, and in situ testing of materials.
The faculty in the Mechanics of Materials Research Group conduct research and offer coursework involving topics at the interface of materials science and mechanics of materials. A major theme is the incorporation of materials structure-property relations in approaches suitable for engineering analysis. A combination of experimental mechanics, analytical and computational micromechanics, and theoretical developments are employed to develop these approaches. ff782bc1db
