The verification of a new approach to the experimental estimation of tensile forces in prestressed structural elements by method based on the magnetoelastic principle

MATEC Web of Conferences, 2017
There are a large number of civil engineering structures where the important structural elements are loaded by large tensile forces. In many practical cases, it is significant to know the current value of tensile force or prestressed stress in these ...

Research on Tensile Stress–Strain Relationship of Azide Polyether Propellant for Wide‐Temperature Range Based on Time–Temperature Superposition Principle

Propellants, Explosives, Pyrotechnics
ABSTRACTAzide polyether propellants are emerging high‐energy solid propellants and have broad application prospects. To determine their mechanical properties under wide temperature ranges, tensile tests were conducted considering different combinations of temperature and loading rate, and the corresponding tensile stress–strain curves were plotted. The

Principle of local symmetry in mixed-mode fracture

Communications Physics
When brittle materials are subjected to uniaxial tensile stress, we observe planar crack propagation perpendicular to the loading direction. However, when additionally subjected to an out-of-plane shear stress, the crack tip/front deviates, leading to ...
