TL;DR: In this paper, the flexural rigidity of a honeycomb consisting of regular hexagonal cells is investigated, and it is found that the bending deformation of the honeycomb cannot be evaluated by using the equivalent elastic moduli obtained from the in-plane deformation since the moments acting on inclined walls of honeycomb cell are different for the inplane deformations and bending deformations.

TL;DR: In this paper, the axial forces and the flexural stiffness of the end constraints of a tie-beams of arches and vaults were derived by one vibration frequency and three components of the corresponding mode shape.

TL;DR: One hundred one consecutive uncemented hip arthroplasties were analyzed radiographically at 1-year follow up to relate mechanical factors to hip pain as determined by clinical pain scores, suggesting that both applied stress and bending stiffness have an effect on pain.
Abstract: One hundred one consecutive uncemented hip arthroplasties (87 patients) were analyzed radiographically at 1-year follow up to relate mechanical factors to hip pain as determined by clinical pain scores. The average area moment of inertia and flexural rigidity were greater for the bone than the metal prosthesis for each type of prosthesis (AML, HG, PCA). Normalization of the flexural rigidity ratio (bone to prosthesis) for patient weight yielded a Spearman correlation coefficient of 0.232, significant at P = .02, suggesting that both applied stress and bending stiffness have an effect on pain. No relationship was seen between pain and AP, or average gap between prostheses and bone.

TL;DR: In this paper, a deflection-hardening hybrid fiber-reinforced concrete (HyFRC) mixture design was developed to enhance material flowability and cohesiveness while maintaining flexural strength.
Abstract: Using a predetermined performance criterion as a basis, there was development of a deflection-hardening hybrid fiber-reinforced concrete (HyFRC) mixture design. There also was investigation of various hybrid and nonhybrid fiber combinations. There was demonstration, through flexural tests and consistency measurements, that material flowability and cohesiveness can be enhanced while maintaining flexural strength through a concrete-based matrix used with a hybrid fiber combination. Four-point bending was used to cast and test HyFRC beam elements, and there was comparison of results against plain concrete control beam flexural performance with and without conventional steel reinforcement. Post-crack flexural stiffness can be enhanced while lower yield strengths can be maintained in HyFRC with reinforcing bar at 0.3% reinforcing ratios in comparison to a reinforced plain concrete element with a 1.1% reinforcing ratio.

TL;DR: In this article, a nonlinear inelastic analysis of composite steel-concrete frameworks using only one element per physical member is presented. But the authors do not consider the effect of material imperfections such as residual stresses.
