... different welding parameters and surface and heat treatments affect the fatigue strength of the structure. In particular, it was evaluated how the gap between two tubes at the beginning of the welding process affects the fatigue strength. Therefore, test specimens without a gap, with a gap of 2 mm...

... in the advanced gas-cooled reactors (AGRs) and Magnox reactors. The AGR study focused on the static Young's modulus, three-point bend strength of unnotched and notched beams, and the work of fracture. The Magnox study focused on the coefficient of thermal expansion, diametral compression, and flexural strength...

... design. A key design criterion of the engineered design method is that the designer know the veneer tie stiffness and strength. However, there is no standard method for testing veneer ties that captures these properties. This paper proposes a conceptual standard for veneer tie testing. In this proposed...

... (geometry and/or volume) may not be compliant with measurement standards and this issue is investigated in the context of graphite strength. Theoretical considerations on stress distribution, together with a review of experimental work based upon Gilsocarbon nuclear graphite IM1-24, are presented...

... This paper will discuss four mechanisms for scale effects in the strength of graphite, two of which originate from the amorphous structure of graphite. The main focus of the paper will be a theoretical investigation into one of these: the case when the micro-scale structure affects the scaling...

... Hydrated lime can be used as a cement replacement in concrete. There are, as there have always been, two critical issues with this type of cement replacement: the change in physical properties with respect to compressive strength, and the cost analysis of the alternatives. The first stage...

... for establishing the long-term hydrostatic strength of these compounds, and how that strength has been successfully used in designing these systems. This paper will give an overview of the basic methodology used to establish the long-term hydrostatic strength of thermoplastic compounds, and how that strength...

... The present research is aimed at investigating effects of concrete properties, particularly concrete rapid chloride permeability, strength, and air void parameters, on freezing-thawing (FT) resistance. In this study, concrete mixtures are made with different types of cement (Types I with 15...

The effect of tube wall friction on the microstructure of Ariake clay samples obtained from a small diameter sampler (45-mm sampler) and their strength and consolidation properties are examined from use of a color laser three-dimensional profile microscope plus unconfined compression, triaxial...

... Snowboard manufacturers attempt to design boards with mechanical properties that provide desirable ride and handling characteristics, adequate strength, and low manufacturing costs. Snowboards are typically a sandwich composite of several individual layers that vary significantly in geometry...

... The objective of this paper is to describe the bolted joint analysis method developed and used by LM Aeronautics (named IBOLT) including the theoretical basis, required input, and coupon-level strength-prediction validation. IBOLT performs a fracture-mechanics-based static strength prediction...
