Evaluating Energy Absorption Performance of Filled Lattice Structures
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Damage evolution and fracture in terms of the theory of phase transition
Abstract The development of many fields of science proves the usefulness of the interdisciplinary approach to the phenomena under investigation, based on the physical analogy of the described processes and their general laws. So, it is known the similarity of the relations obtained by J. Gibbs and A.

Multifield Coupling Mechanism of Unloading Deformation and Fracture of Composite Coal-Rock
The deformation and fracture evolution of coal and rock under unloading are prone to sudden instability or dynamic damage. To solve the problem, this paper combines interdisciplinary theories such as damage mechanics and electromagnetic field theory. The

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Meso-mechanism of rock failure influenced by bolt anchorage under uniaxial compression loading
As an important support method, the bolt anchoring system is widely used to control the dynamic disasters of deep brittle surrounding rock, but deep rock engineering practices have been beset by the failure of brittle rock with bolt support because the ...

A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...
