Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

The study of the relation model between elastic modulus and porosity in deep coal seam roof sandstone

矿业科学学报, 2019
Rock mass’s elastic modulus is closely related to its compositions,inner structural characteristics and stress-strain state.By assuming the elastic modulus of pore that as a part of rock is zero,a relational model between the elastic modulus of the whole

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

A dynamic damage constitutive model considering the effect of joint inclination on the modulus of elasticity of slates

Scientific Reports
The dynamic damage constitutive model has limitations and needs to reflect the quantitative relationship between the elastic modulus and joint inclination angle of the slate.

Study on the size effect of rock elastic modulus considering the influence of joint roughness

Frontiers in Materials
The elastic modulus of rocks is a measure of the ability of rocks to resist elastic deformation. It is related to the size of rocks and can effectively measure the internal physical and mechanical strength of rocks.

Micro-Raman structural responses of nano-mechanical properties of different coal grades

Meikuang Anquan, 2022
The mechanical properties of coal are heterogeneous and in multi-scale. Understanding the coal mechanical properties and structure in nano-scale is the key to know the fracturing transformation and crack expansion mechanisms of coal reservoirs.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Experimental study on LBL beams [PDF]

MATEC Web of Conferences, 2019
Six specimens were made and tested to study the mechanical properties of LBL beams. The mean ultimate loading value is 68.39 MPa with a standard deviation of 6.37 MPa, giving a characteristic strength (expected to be exceeded by 95% of specimens) of 57 ...
