1. Finite element computational development for thermo-mechanical analysis of plane steel structures exposed to fire
Abstract This article presents a numerical formulation based on finite element procedures for application in nonlinear thermo-mechanical analyses of steel planar structures under fire condition. The mechanical properties of structural elements degrade when subjected to high temperatures, resulting in significant reductions in strength and stiffness. Under th

2. Evaluation of Dynamic Mechanical Properties of Fique Fabric/Epoxy Composites
The fique is a plant typical of the Colombian Andes, from which relatively common items are fabricated. One of these is woven fabric extensively applied in sackcloths. The mechanical strength of fique fabric have motivated recent investigations on possible reinforcement of polymer matrix composites. For this purpose its thermo-mechanical behavior was unveile

3. Evaluation of two-step transformation in Ni-rich titanium-nickel alloys using thermal and internal friction analyses
ABSTRACT The use of Ti-Ni memory alloys covers several fields of application such as medicine, dentistry, actuators, sensors among others. Because of the thermomechanical behavior of these materials, they are an object of continuous studies and their properties are related to the occurrence of thermoelastic martensitic phase transformations. The thermal anal

7. Thermo-mechanical analysis of mass concrete elements made of rubberized concrete
Resumo Neste estudo, foram avaliadas amostras de concreto massa com borracha (concreto emborrachado) para determinar se a adição de partículas de borracha aumentaria a resistência à fissuração devido a variações volumétricas de origem térmica, em comparação com um concreto de referência, sem borracha. Amostras dos concretos estudados foram inic

8. Effect of Extrusion and Heat Treatment on Microstructure and Mechanical Properties of Hypereutectic A390-0.3wt%Nd Alloy
An hypereutectic aluminium alloy with a composition of 16-18wt%Si, 4-5wt%Cu, 0.45-0.65wt%Mg, 0.3wt%Nd and Al balance (A390-0.3wt%Nd alloy) was processed by extrusion and aging at 200ºC for 10 hours. The effect of the thermomechanical processing and heat treatment on microstructure and mechanical properties was investigated for A390-0.3wt%Nd alloy. It was sh

10. Application of ashes as filling in reprocessed polypropylene: thermomechanical properties of composites
Abstract The life cycle of a product depends to a great extent on its reuse and ease of recycling. This work had developed of composite materials of reprocessed polypropylene composites with rice husk ash (RHA) and sugarcane bagasse ash (SBA) through the coextrusion and injection processes as main purpose. The polymeric matrix was reprocesed until six gener

11. Thermomechanical Properties of Corn Starch Based Film Reinforced with Coffee Ground Waste as Renewable Resource
Abstract Starches polymeric films offer several advantages for the replacement of synthetic polymers due to their biodegradability, non-toxicity, availability and low cost. However, the high biodegradation potential can cause fragility, considering some fundamental mechanical properties. Therefore, starch based polymeric films were reinforced incorporating l

12. Mechanical behavior and water absorption in sisal/glass hybrid composites
ABSTRACT This study aimed to assess the effect of hybridization on thermomechanical properties and water absorption of composite materials, by introducing sisal fiber tissue into the material. To that end, two composite material plates were manufactured, the first with five layers of E-glass reinforcement mat and the second with three layers of E-glass fiber
