Stress Strain Curve For Mild Steel - Mechtics

Different material may have different curve. Usually ductile materials follow similar pattern., so is for brittle materials. Here is the explanation of stress strain curve for mild steel which is ductile material. Here is the list of different stages when ductile material subjected to force till its failure. Proportional limit (point A)

Properties of Concrete at Elevated Temperatures

Fire response of concrete structural members is dependent on the thermal, mechanical, and deformation properties of concrete. These properties vary significantly with temperature and also depend on the composition and characteristics of concrete batch mix as well as heating rate and other environmental conditions. In this chapter, the key characteristics of concrete are outlined.

fatigue of concrete Topic

Concrete fatigue refers to the phenomenon of rupture under repeated loadings, each of which is smaller than a single static load that exceeds the strength of the material. Fatigue is exhibited when a material fails under stress applied by direct tension or compression, torsion, bending, or a combination of these actions.

Rheology - Wikipedia

Rheology (/ r iː ˈ ɒ l ə dʒ i /; from Greek ῥέω rhéō, 'flow' and -λoγία, -logia, 'study of') is the study of the flow of matter, primarily in a liquid or gas state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force.Rheology is a branch of physics, and it is the science

Behaviour of cracked reinforced concrete beams under

This paper compares the behaviour of reinforced concrete beams subjected to sustained and repeated load types in bending. Mid-span deflections and surface strain profiles were monitored over an 80 day period so that comparisons could be made between the structural response of RC (reinforced concrete) beams to the different load types tested.

Shear Behavior of Hybrid Fiber Reinforced Concrete ... - MDPI

Hybrid fiber reinforced concrete (HFRC) is based on a multilevel-reinforcement material design that improves both the compressive strength and tensile strength. Investigations of the mechanical performance of HFRC with two types of steel fibers were conducted experimentally. The investigated parameters were the volume fractions of the short steel fibers and long steel fibers.

Tensile Behavior of Carbon Fiber-Reinforced Polymer

This study experimentally examined the effect of nanomaterial on the tensile behavior of carbon fiber-reinforced polymer (CFRP) composites. Multiwalled carbon nanotubes (MWCNT), graphene nanoplatelets (GnPs), and short multiwalled carbon nanotubes functionalized COOH (S-MWCNT-COOH) with 1% by weight were used as the primary test parameters.

Stress-Strain Behaviour of Concrete

Concrete belongs to a class of materials that can be called ‘Strain – softening’, indicating a reduction in stress beyond the peak value with an increase in the deformation (as against the strain hardening behaviour commonly exhibited by metals like steel). Figure 3 shows different types of material behaviour. Figure 3. Different
