• The principle of virtual energy (PVE) is established based on the modern thermodynamics for the accurate prediction of material strength. • Some examples are presented to show the universality and feasibility of the principle, demonstrating its excellent prospects for all engineering applications. • It is found that material strength may not be an intrinsic property of the material but rather a property of the material specimen. As a matter of safety, the reliable prediction of the structural failure of materials is the most important key issue for various types of engineered structures. Traditional theories of material strength mainly rely on empirical formulas. Although there are a variety of strength theories available in the literature, they are largely limited by the materials and working conditions of their application. To ensure safety, engineering structures are often designed with large safety factors, resulting in a significant use of material resources. However, this still cannot eliminate the occurrence of catastrophic accidents. Recently, the author developed a thermodynamic framework, referred to as the thermodynamic strength theory (TST) [Eng. Fract. Mech., 2021, 254: 107936; Adv. in Mech., 2023, 53: 693–712.], to accurately predict the failure strength of engineering material structures. In this paper, the principle of virtual energy (PVE) is established based on the modern thermodynamics for the practical application in engineering. For a given imaginary small change in the key state variables of a material system, one can establish a failure strength criterion for the loaded material structure by investigating the induced change in the free energy. Some examples are presented to show the universality and feasibility of the principle, which demonstrates its excellent prospects for all engineering applications. [ABSTRACT FROM AUTHOR]

This article presents information on the book "Mechanics of Elastic Composites," by Nicolaie Dan Cristescu, Eduard Marius Cradun, and Eugen Soós. Composite materials play a fundamental role in many modern engineering applications and have been the focus of much research and development in recent years. This book discusses the theory that provides the foundation for these materials. Beginning with an introductory review of tensor calculus and the fundamentals of linear elastostatics, the authors explore the advanced, three-dimensional theory of elastic composites, from the classical aspects of laminates to recently developed results and methods related to the buckling of fiber-reinforced composite strips, stability analysis of composite laminates, and brittle fracture mechanics.

In this article, the developed numerical techniques for assessment of deformation and fracture response of ferritic steel during its manufacturing are considered. Because microdefects of ferritic steel are thought to nucleate at second-phase particles, the formulated strategy for evaluating these particles uses standardized experimental fracture tests with micromechanical FEM simulations of microdefect evolution in the material. The evolution of the microdefects is described by an enhanced Gurson-type model incorporating effects of the microvoid aspect ratio. An estimate of the objective function for material parameters of the Gurson-type model is provided by the Kalman filtering technique. Their best fit set of the material parameters is established by the search scheme of the evolution strategy according to the density, size, and spatial distribution of second-phase particles in the material. Some examples are presented to demonstrate that the evolution strategy can be used to optimize important processes of steel manufacturing in the context of strength and toughness of critical parts.
