Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe<sub>2</sub>. [PDF]
Adv MaterAbstractLocal deformation is a control knob to dynamically tune the electronic band structure of 2D semiconductors. This study demonstrates the local strain‐dependent phonon properties of monolayer tungsten diselenide, which are investigated by using the scanning tunneling microscopy‐based tip‐enhanced Raman spectroscopy.

IOP Conference Series: Materials Science and Engineering, 2023 Abstract To reduce computation time, the inherent strain (IS) method is popular. It consists in adding layers, at room temperature, with an “inherent strain” representing the plastic deformation undergone during deposition. An IS method is developed, including a direct determination of the IS tensor based on the transient thermo-elastic ...

Multi-Pass Welding Distortion Analysis Using Layered Shell Elements Based on Inherent Strain
Journal of Marine Science and Engineering, 2021 In this article, a layered shell element-based, elastic finite element method for predicting welding distortion in multi-pass welding is developed. The welding distortion generated in each pass can be predicted by employing layer-by-layer equivalent ...

Empirical methodology to determine inherent strains in additive manufacturing [PDF]
Computers & Mathematics with Applications, 2019 Part distortion is a critical issue during Additive Manufacturing (AM) of metallic parts since it prevents this technology from being implemented at industrial level. To this regard, distortion prediction even from design stage has become crucial. Actually, numerical modelling methodologies play an important role here.
