Distribution fitting for long term electric field strength measurements
2017 40th International Conference on Telecommunications and Signal Processing (TSP), 2017As a result of the enormous increase in usage of wireless systems; electromagnetic radiation (EMR) sources in residential areas as well as the exposed EMR levels has increased significantly. Therefore this study aims to determine the exposed E levels and characterize the electromagnetic environment on the basis of long term (24 hours) E measurements ...

Strength of Materials, 1974
1. The system of creep equations (1), or respectively (11), fairly well reflecting the mechanical basis of the process and embracing all stages of creep, does not create additional mathematical difficulties, when solving concrete problems. 2.

Creep and long-term strength of magnesia ceramics
Refractories, 1972A study was made of the creep and long-term strength of magnesium oxide ceramics with crystal sizes of 12 and 25μ at 1400–1550°C and 200–600 kg/cm2. Ceramics with smaller crystal sizes are characterized, in identical conditions, by a higher creep rate, but lower long-term strength.

Long-term strength and creep of aluminum alloys
Metal Science and Heat Treatment, 19791. Increasing the static loading time for aluminum alloys AMg6, 1201, and 1911 at standard temperature to 2000 h leads to a reduction of the strength by 10–20% and the ductility by 10–15%. 2. The buildup of creep strain increases considerably with increasing stress and is characterized by isochronous deformation curves, in accordance ...

Fatigue and Long Term Strength of Thermoplastics
1986Thermoplastics are complex materials in their response to applied loads. They do not obey Hooke’s law, being non-linear in their relationship between stress and strain. They are also viscoelastic in nature. This property is seen either as a time dependent response in stress (stress relaxation), when held under conditions of constant strain, or as a ...

Long-Term Strength Development of Controlled Low-Strength Material
ACI Materials Journal, 2002This paper presents results of an experimental study conducted to evaluate the combined effects of prolonged mixing time, late water inclusion, and variations in total water content on the long-term compressive strength of controlled low-strength material (CLSM). Long-term strengths refer to strengths measured after 600 days of curing.

Long Term Strength of Structural Adhesive Joints
The Journal of Adhesion, 1972Abstract The long term static strength of adhesive joints is analyzed in terms of a modified Prot method and sustained load tests. Data from the failure times under different loading rates are used to predict the static stress that an adhesive joint will withstand for an infinite time, i.e., the endurance limit.

Long‐Term Strength Development of Pavement Concretes
Journal of Materials in Civil Engineering, 1994Development of pavement concrete compressive strength, flexural strength, and splitting tensile strength as a function of time is discussed. Eighteen sets of post‐1985 exerimental data from academic and industrial sources were selected to form a database of strength data for “modern” pavement concrete.
