Understanding the frontier difference between building information modeling (BIM) research and practice is a top priority to guarantee the engineering significance and feasibility of academic achievements, yet such research gap has not been well-explored. The purpose of this paper is to provide an objective and accurate analysis of BIM knowledge using 551 published BIM-related papers and 68 documents of frontier BIM projects in China.

This paper adopts the mixed method, combining the bibliometrics method with the qualitative method. Bibliometrics was used to analyze 551 BIM-related literatures from China with Citespace 5.0. Qualitative research was used to analyze 68 project documents from China with Nvivo. Finally, the analysis results are compared to obtain the final conclusion.

The analysis results of the collected BIM-related papers, given by bibliometrics analysis, show that the subject categories of engineering, civil engineering, and construction and building technology, and 8 key research clusters are extremely important for development of BIM knowledge. The analysis results of the collected project documents, given by qualitative analysis, indicate that visualization, aided management, intelligent construction, simulation and analysis are the hot applications of BIM practice.

Through comparison, certain research gaps between the research and practice community in China was identified, which are useful for identification of research trends and practice frontier in BIM community. This study offers useful and new insights to summarize the status quo of BIM and can be used as a reference to integrate future BIM developments.

The strength of printed parts by application of fused deposition modeling (FDM) has been broadly studied through experimental methods. However, constitutive behaviors of the printed parts in theory are still unclear. Therefore, this paper aims to focus on building an elasto-plastic model of the printed parts to reveal the constitutive behavior.

An elasto-plastic constitutive model that considers anisotropic characteristics is proposed. Tensile tests are performed for parameter identification by using different samples with varying printing angles. Finally, the constitutive model is completed and applied to the numerical analysis of a tensile procedure.

The experimental study indicated that the anisotropic characteristics are significant for elastic modulus and strength of printed parts. The polar anisotropic model is suitable for describing the anisotropic behavior of parts during the elastic deformation. The Hill model is suitable to describe the yield property. The elastic modulus and yield point of parts printed in any specific orientation can be calculated using the proposed constitutive model.

A theoretical model has been developed to describe the constitutive behavior of FDM printed part. This model can precisely describe the elastic behavior and yield point of parts printed with various orientations. This model can be applied to the finite element simulation of printed structures.

The study aims to investigate the effects of bodily feelings on preference for robotic service by examining direct and indirect sensations from physical and metaphorically projected bodily feelings.

Through four empirical experiments involving video and recall tasks to metaphorically manipulate participants’ bodily warmth and directly manipulate ambient temperature, the authors explored the mediating role of the need for warmth and the moderating role of robotic features (warmth vs competence) on consumer willingness to engage with and pay for robotic services.

Warmth perception exhibits a positive correlation with robotic services. This relationship is mediated by the need for warmth. Moreover, when customers experience a sensation of physical warmth, they show a greater willingness to pay for a robotic service exhibiting competence versus warmth.

This research contributes to the literature by integrating the feelings-as-information theory and the mind perception view to understand the judgment of robotic services. It extends the application of the embodied cognition theory, highlighting the significance of bodily feelings as a source of information in customer decision-making processes. Furthermore, this research explores the metaphoric influence of service features on bodily responses, providing new insights into the role of embodiment and mental perception in robotic service evaluations.

Managers should consider using different robots based on seasonal settings to meet customers’ need for warmth. Understanding customers’ bodily feelings and the metaphoric influence of service features contributes to the design of more effective and customer-centric robotic services.

This inquiry explores the metaphoric influence of service features on bodily responses, providing new insights into the role of embodiment and mental perception in robotic service evaluations.
