Stress Essays Stress Essay Stress Essay Stress is the loading applied   on the material while strain is the deformation that results due to application of load or stress. By this definition, it is obvious that stress and strain are related and that relationship can best be explained by considering a stress-strain curve (Figure 1). Building materials have their own corresponding stress-strain curve which can be obtained by recording the amount of deformation (strain) upon application of tensile or compressive loading. Curve results reveal the behavior or properties of materials when load (weight) is applied.Figure1. Stress-Strain curveConsider the Stress-Strain curve of building materials in Figure 1. For concrete materials, its curve is almost a straight line and ends rather abruptly. This means that concretes easily fractures or fails (brittle material).
