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.

Comparative Study on the Test Method for Tensile Elastic Modulus of Rock Materials

Advances in Civil Engineering, 2019
Rock material has different mechanical behaviors under compressive and tensile loading. Correspondingly, there are two types of elastic modulus: compressive elastic modulus Ec and tensile elastic modulus Et, respectively.

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.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

Advanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Mechanics of plant fruit hooks

, 2013
Hook-like surface structures, observed in some plant species, play an important role in the process of plant growth and seed dispersal. In this study, we developed an elastic model and further used it to investigate the mechanical behaviour of fruit ...

Association Between Atherosclerosis in Carotid Artery and Elastic Modulus of Brachial Artery [PDF]

Journal of Tehran University Heart Center, 2007
Background: Common carotid arterial stiffness can be assessed during carotid arterial ultrasonography, but its association with brachial stiffness, a well-defined cardiovascular risk factor, has not been clarified.

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 ...

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
