Introduction Civil structures are continuously degraded due to unexpected loading, environmental changes and natural degradation of materials among other factors.
However, the material properties of the PSC bridge girder could not be evaluated on the site.
It can be assumed that the support stiffness is higher than that of the general material.

Introduction Hydrogen-assisted mechanical degradation of structural materials is one of the most complex phenomena of the metallic materials degradation, due to several new unknowns in the degradation process kinetics, compared to the degradation in the absence of hydrogen in metal.
Hydrogen may degrade the mechanical behavior of metallic materials, including steel, and lead them to failure.

Introduction The study of bio-inspired materials and surfaces has been a rapidly growing area of research in recent years [1], focusing on creating new and improved materials that mimic the structures and functions of natural materials.
Absorptance is essential in various engineering and materials science applications, including solar panels, energy-efficient windows, optical coatings, and filters.
This property is crucial in various engineering and materials science applications, including optical filters, lenses, transparent conductors, solar panels, and energy-efficient windows.
In engineering and materials science, friction is a critical factor in many applications.
A differential characteristic of 3D printing is a wider applicability for different materials (ceramic, metal, or polymeric phases) and even for hybrid materials.
