Evaluation of Electromagnetic Pulse Shielding Performance of Carbon Fiber-Mixed Cement Paste

International Journal of Concrete Structures and Materials, 2022
This study investigated the physical properties and electromagnetic pulse (EMP) shielding performance of cement paste containing small-diameter carbon fibers to develop an EMP-shielding cement. Small-diameter carbon fibers were used as a cement admixture

On the choice of the thickness of the cement mantle in cemented hip arthroplasty

Journal of Theoretical and Applied Mechanics, 2017
Recommendations for the optimal thickness of the cement mantle in cemented hip arthroplasty are outlined based on the results obtained with the finite element method. The investigations show that distal femur cement thickness higher than 2mm positively affects mechanical behaviour of the cement mantle and can be useful in reducing stress-strain ...

Stress distribution in pediatric zirconia crowns depending on different tooth preparation and cement type: a finite element analysis

BMC Oral Health, 2022
Background In clinical settings, tooth preparation for prefabricated zirconia crowns (PZCs) in the primary dentition varies widely. However, knowledge about the biomechanical behavior of PZCs in various clinical settings is limited.

The Effect of Layer Variation Between Liner and Cement Mantle on Reducing Cracks of PMMA Material Hip Joints

E3S Web of Conferences, 2018
Failure of cement mantle of bond loosening between liner and cement mantle is an important issue in total hip replacement. Two factors that commonly cause cement mantle failure are initial crack and stress.
