The slip activity during the transition from elastic to plastic tensile deformation of the Mg-Al-Mn sheet

Journal of Magnesium and Alloys, 2021
The deformation behavior of the Mg-Al-Mn sheet was investigated during tensile loading along the rolling (RD) and transversal direction (TD) with special attention to the early stage of deformation.

Direct evidence of an increasing mutational load in humans [PDF]

Molecular Biology and Evolution, 2018
Abstract The extent to which selection has shaped present-day human populations has attracted intense scrutiny, and examples of local adaptations abound. However, the evolutionary trajectory of alleles that, today, are deleterious has received much less attention.

Deformation mechanisms in ice-templated alumina–epoxy composites for the different directions of uniaxial compressive loading

, 2021
The ice-templating technique enables the fabrication of multilayered ceramic-based composite materials. Very little is known on the inelastic deformation mechanisms that evolve in this class of composite materials under compressive loading conditions and

Cooperative activities of forearm muscles under loading applied to thumb or each finger

Journal of Biomechanical Science and Engineering, 2018
Human thumb and fingers are usually subjected to an external loading during daily activity. The information of how muscles in the forearm cooperate with each other in order to response to the external loading is still unknown.

Analysis of relationship between loading condition and cranial cracking pattern using a three-dimensional finite element model

BMC Musculoskeletal Disorders, 2022
Background A hairline crack on the cranium can occur even under a small external load or impact and are thus often observed in patients who have experienced an accidental fall or collision.
