Simulation on strength and thermal shrinkage property mechanisms of pre-cracked cement stabilized crushed stone [PDF]

, 2022
For the problem that the cement stabilized crushed stone tends to develop cracks, thus reducing the service life of pavements, an idea based on the coarse aggregate pretreatment technology was proposed to improve the pre-cracked cement stabilized crushed

Modeling the Cupping of Lumber

BioResources, 2016
Wood shrinks anisotropically as it loses hygroscopic moisture. While longitudinal shrinkage (parallel to the grain) is nearly negligible in normal wood, transverse shrinkage (across the grain) is significant and characterized as tangential and radial ...

Determination of residual stress evolution during repair welding of high-strength steel components

Forces in Mechanics, 2022
During the assembly of steel structures, unacceptable weld defects may be found. An economical solution is local thermal gouging of the affected areas and re-welding.

Application of a Novel Chamfered Mold to Suppress Corner Transverse Cracking of Micro-Alloyed Steel Slabs

Metals, 2020
A novel chamfered mold is developed to solve the problem of corner transverse cracking in micro-alloyed steel slabs. The shape of the slab was changed from four corners and sides to eight corners and sides due to the use of a chamfered mold.

Micromechanical FE analysis on thermal residual stress and shrinkage behavior of 2.5D woven Cf/Al composites

Journal of Aeronautical Materials, 2022
2.5D woven Cf/Al composites were fabricated by vacuum-assisted pressure infiltration method. Thermal shrinkage behavior and residual stress of the composites were investigated using micromechanical analysis and experimental method.

Effect of line heating factors on transverse shrinkage generated by triangle heating

Journal of the Society of Naval Architects of Japan, 2003
For automatization of the line heating work that is a basic technology in making curved surfaces of ships it needs to evaluate transverse shrinkage generated by triangle heating quantitatively. In this paper, techniques were examined in triangle heating tests and an estimation method using FEM analyses were developed in the first place.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Predicting Welding-Induced Transverse Shrinkage in H-Shaped Steel Beams Using a Merged Weld-Pass-Shrinkage Function-Equivalent Indirect Action Framework

Buildings
On-site multi-pass welding in building steel structures often induces transverse shrinkage, affecting assembly accuracy and final geometry. Pass-by-pass thermo-elasto-plastic simulation can capture the welding process but is computationally expensive for
