Abstract

Purpose

The purpose of this paper is to examine the effect of internal pores on the tensile properties of a Co–Cr–Mo alloy fabricated by selective laser melting (SLM).

Design/methodology/approach

The size and volume fraction of pores were controlled through high temperature annealing (HTA) and hot isostatic pressing (HIP).

Findings

After HTA, the size and fraction of pores decreased compared with the as-built SLM sample, and no pores were observed after HIP. Tensile tests of the HTA and HIP samples showed nearly similar tensile deformation behavior. From the results, the authors found that the size of the internal pores formed in the SLM process had little effect on the tensile properties. The as-built SLM sample had less elongation than the HTA and HIP samples, which would not the effect of porosity, but rather the effect of the residual stress and the retained ε phase after the SLM process.

Originality/value

Although pores are a main factor that influence the mechanical properties, the effect of pores on the tensile properties of Co–Cr–Mo alloys fabricated by SLM has not been studied. Therefore, in this study, the effect of pores on the tensile properties of a Co–Cr–Mo alloy fabricated by SLM was studied.

Abstract

Purpose

The purpose of this paper is to develop a similarity evaluation method between virtual and actual clothing.

Design/methodology/approach

The paper analyzes the subjective and objective evaluation results of virtual and actual clothing.

Findings

In this paper, significant factors affecting the evaluation of similarity between actual and virtual clothing have been found.

Research limitations/implications

Evaluation experiment was performed only for a skirt. However, the method can be easily applied for other types of garments.

Practical implications

The evaluation of similarity between actual and virtual garment will be facilitated.

Social implications

The garment design process can be facilitated by simulating garments in virtual space.

Originality/value

There has not been any quantitative evaluation method for the similarity of virtual and actual garment.

Abstract

Purpose

The purpose of this paper is to illustrate the generation of basic garment pattern using three‐dimensional body measurement data.

Design/methodology/approach

A pre‐defined garment model is deformed using free‐form deformation method and the model is flattened to generate flat patterns.

Findings

The paper finds that individual basic garment patterns are automatically generated and verified to be well fit on human subjects.

Research limitations/implications

The current approach is to focus on the generation of basic bodice patterns; however, other patterns can also be generated by this method by preparing more garment models.

Practical implications

This method can reduce the time required to design basic patterns as well as enhance their fitness.

Originality/value

The automatic generation of individually fitted garment pattern is one of the most important steps in future garment production process.

Abstract

This paper investigates a retrospective on the Journal of Derivatives and Quantitative Studies (JDQS) on its 30th anniversary based on bibliometric. JDQSs yearly publications, citations, impact factors, and centrality indices grew up in early 2010s, and diminished in 2020. Keyword network analysis reveals the JDQS's main keywords including behavioral finance, implied volatility, information asymmetry, price discovery, KOSPI200 futures, volatility, and KOSPI200 options. Citations of JDQS articles are mainly driven by article age, demeaned age squared, conference, nonacademic authors and language. In comparison between number of views and downloads for JDQS articles, we find that recent changes in publisher and editorial and publishing policies have increased visibility of JDQS.
