El desarrollo de los países está generando una serie de problemas a nivel mundial que están provocando cambios en el clima, que en la mayoría de los casos afectan en gran medida a las familias con menores recursos. De igual ...
Calibration patterns for predicting residual strengths of steel fibre reinforced concrete (SFRC)
(Elsevier, 2013-11-12)
Steel Fibre Reinforced Concrete (SFRC), a composite construction material, needs reliable prediction and control techniques to promote its use in structural applications. The distribution and orientation of fibres within ...
Experimental Investigations of Using Aluminum Oxide (Al2O3) and Nano-Graphene Powder in the Electrical Discharge Machining of Titanium Alloy
(MDPI, 2023-12-16)
In the present study, a comprehensive parametric analysis was carried out using the electrical discharge machining of Ti6Al4V, using pulse-on time, current, and pulse-off time as input factors with output measures of surface ...
Modeling the environmental sustainability of timber structures: a case study
(Elsevier, 2019-07-16)
A revival in timber buildings and the appreciation of their positive physical and mechanical properties can be explained by the unique environmental credentials of timber products and their versatility. Heightened public ...
The Weldability of Duplex Stainless-Steel in Structural Components to Withstand Corrosive Marine Environments
(MDPI, 2020-11-05)
There is still a considerable gap in the definition of the weldability of Duplex Stainless Steel (DSS). A lack of clarity that is explained by the standard specification of the maximum content of equivalent carbon that ...
Sustainability Improvement in the Design of Lightweight Roofs: A New Prototype of Hybrid Steel and Wood Purlins
(MDPI, 2019-01-01)
A new structural typology of a hybrid purlin, made of type C cold steel and rectangular laminated wood (SWP), is presented in this paper. As a result, improvements on the most commonly used steel purlins are achieved, by ...
Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts
(MDPI, 2018-06)
Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to ...
