Deep learning-based predictions of process parameters for thick composites laminates manufacturing (2022)
Presentation / Conference
Ammasai Sengodan, G., Hoang Luong, M., & A Ponnusami, S. (2022, September). Deep learning-based predictions of process parameters for thick composites laminates manufacturing

In a composite manufacturing process, the tool geometry and thermal characteristics of the bagging materials dictate the heat transfer mechanism. The temperature distribution, resin chemical kinetics and residual thermal strains determine the cured p...

Numerical modelling of the effects of temperature and moisture on mechanical response (2019)
Presentation / Conference
Ammasai Sengodan, G., Allegri, G., & Hallett, S. (2019, September). Numerical modelling of the effects of temperature and moisture on mechanical response. Presented at 7th ECCOMAS Thematic Conference on Mechanical Response of Composites, University of Girona, Girona, Spain

Hi-fidelity finite element models with physically based failure criteria are now well established for fiber reinforced composites, giving good accuracy at standard room temperature conditions. However, the mechanical properties of fiber reinforced co... Read More about Numerical modelling of the effects of temperature and moisture on mechanical response.

Thermo-mechanical de-bonding of composite-titanium single-lap adhesive joints (2017)
Presentation / Conference
Ammasai Sengodan, G. (2017, August). Thermo-mechanical de-bonding of composite-titanium single-lap adhesive joints. Presented at 21st International Conference on Composite Materials, Xi'an, China

The aim of this work is to isolate the constituent adherends of the adhesively bonded single lap joints with minimal or no damage to them and prepare the debonded surfaces for re-bonding. Thermo-mechanical separation of carbon fiber reinforced plasti... Read More about Thermo-mechanical de-bonding of composite-titanium single-lap adhesive joints.

A parametric study on strength and stiffness of hybrid scarf joints (2017)
Presentation / Conference
Shankar, S., Ammasai Sengodan, G., & Idapalpati, S. (2017, August). A parametric study on strength and stiffness of hybrid scarf joints. Presented at ICCM International Conferences on Composite Materials, Xi'an, China

This work presents a parametric study of adhesively bonded scarf joints enriched with mechanical fasteners. Tensile tests of two different fastener positions along the load path were carried out and compared with bonded scarf joint. It was found that...

Aerogel core CFRP curved sandwich composites with variable cross-section without ply-drop for body protection and rehabilitation (2016)
Presentation / Conference
Ammasai Sengodan, G., & Joshi, S. (2016, May). Aerogel core CFRP curved sandwich composites with variable cross-section without ply-drop for body protection and rehabilitation. Presented at SAMPE Long Beach 2016 Conference and Exhibition, Long Beach, United States

A novel method to design and manufacture aerogel core (patented technology) CFRP sandwich composites with variable geometry and mechanical properties without any ply-drop is envisaged, analyzed and demonstrated. Using this method, such composites can... Read More about Aerogel core CFRP curved sandwich composites with variable cross-section without ply-drop for body protection and rehabilitation.

Integrated analysis of compaction, edge distortion and residual deformation of wind-turbine thick composite spar-cap (2015)
Presentation / Conference
Ammasai Sengodan, G., Joshi, S., & Chen, Z. (2015, July). Integrated analysis of compaction, edge distortion and residual deformation of wind-turbine thick composite spar-cap. Presented at ICCM International Conferences on Composite Materials, Copenhagen, Denmark

A scaled model of a unidirectional glass/epoxy wind turbine spar cap measuring 7.5 mm thick was cured in a vacuum assisted oven and noticed a non-uniform thickness along its length. Even though, a vacuum pressure of 1 bar applied to the laminate, the...

Fibre Bragg grating sensors for in-situ measurement of resin pressure in curing composites (2014)
Presentation / Conference
Ammasai Sengodan, G., Maheshwari, M., Joshi, S., Chen, Z., Asundi, A., & Tjin, S. (2014, November). Fibre Bragg grating sensors for in-situ measurement of resin pressure in curing composites. Presented at International Conference on Experimental Mechanics 2014, Singapore

A fibre optic sensor was developed for in-situ pressure measurement based on the principle of differential pressure in liquids. This sensor system is very simple and consists of fibre Bragg grating (FBG) done on a fibre with core diameter of 9 µm....
