He received a BS in Materials Science and Metallurgical Engineering from theUniversity ofCincinnati in and worked at NASA-Lewis as a Materials Research Engineer for two years performing heat treatment and fracture studies of titanium and steel alloys. Southern Research provides a comprehensive range of material mechanical property testing and analysis that supports industrial, aerospace, and military clients. Our experienced engineering team has proven expertise in materials behavior, analysis, and evaluation and is supported by a contingent of highly skilled experimentalist technicians. However, very little is known regarding its mechanical properties at low temperature. This paper presents the results of an experimental study on the mechanical properties of high‐strength concrete in the temperature range between + 20 ° C and ° C (+ 68 ° F and ° F) without considering the effect of freezing cycles. Test results.

T. he mechanical response of materials to different external loadings is of great importance to many fields of science, engineering, and industry. Structural failure is realized when the functionality of engineering components has been depleted. In general, there are three main reasons for a compo- nent to become dysfunctional—excessive (elastic or inelastic) deformation, fracture, and Size: 1MB.

As the temperatures of operating environments increase, however, elevated-temperature properties quickly become the primary concern. The family of stainless steels is most versatile in its ability to meet the requirements of high-temperature service.

An understanding of these property changes is therefore extremely important. Ion irradiation and nanoindentation are common techniques to study these irradation effects, however until now mechanical testing has been limited to room temperature. This is a far cry from the temperatures at which these materials will be in service. The mechanical properties of a material are not constants and often change as a function of temperature, rate of loading, and other conditions. For example, temperatures below room temperature generally cause an increase in strength properties of metallic alloys; while ductility, fracture toughness, and elongation usually decrease.
