Fatigue of internal combustion engine valves

Type Modeling & calculation
Industry Metallurgical
Country ar Argentina
Technologies CAE

Development of a set of input files for Fino and wasora plus Bash scripts to analyze fatigue lifetime of both an admission an exhaust valves of an internal combustion engine and elaboration of a technical report with the main results. The scripts and the report had to be modifiable by the user to be applicable to other products as well. The inclusion of support for non-trivial displacement boundary conditions (i.e. fixation to a conic surface) had to be added to Fino during the course of the project.


Computational implementation of the mathematics behind material fractomechanics

Technologies CAE

Guidance on mathematical methods and computational tools to perform fractomechanical analysis of admission and exhaust valves for internal combustion engines. From the Seamplex’ point of view, the project consisted on a consulting task regarding the computation of volume integrals of deformation energy over CAE grids and analysis of time-dependent variables. Both computations were performed using wasora.

Some tech-based startups needed to manage contractors to develop internet-of-things software for their products. As the “tech” of these startups was not software (but rather electronics and medical devices) they lacked the skills to know if the contractors were providing was was needed. Seamplex assisted the startups (actually the incubator CITES) with these kinds of technical management tasks.


Environmentally-assisted fatigue of dissimilar joints in nuclear power plant pipes

Country ar Argentina
Technologies CAE

Detailed analysis of fatigue under environmentally-assisted conditions of welds over dissimilar materials in pipes of systems directly related to the safety of a heavy-water nuclear power plant. Differential thermal expansion effects over operational and incidental transients had to be considered, including the occurrence of design-basis earthquakes. Stress linearization according to ASME VIII, fatigue analysis according to ASME III and NRC/EPRI computation of water-assisted fatigue factors had to be performed. All in all 24 dissimilar joints were analyzed. Transient heat conduction and quasi-static elasticity was solved with Fino. Fatigue assessment was performed using wasora. All the input files and scripts used to obtain the final results were tracked with Git, and each of the 24 final reports contained the hash of the corresponding calculation repository for full traceability.


Computation of stresses in butterfly valves due to incorrect installation

Country ar Argentina
Technologies CAE

A parametric study of mechanical stresses due to failure to mount flange butterfly valves on the main pipe line as a function of the mis-installation angle was performed. Valves of nominal diameter of 2, 4 & 6 inches were studied. Fino was used as the finite-element solver of the elastic problem. Results were presented in a detailed document reporting the parametric results and the main conclusions.

Technologies AI UNIX

A feasibility study for creating an artificial intelligence tool for assisting into business decisions in a food factory was conducted. A set of Python scripts that attempted to predict data (i.e. prices, consumption, etc.) from past years were coded. Predictions were based on decision trees and Bayessian regressions. They included other external set of data like FIAT currency exchange markets, stock market prices, etc.


Firmware development for IoT devices providing laboratory-as-a-service in the cloud

A new-generation of medical devices working on the cloud (instead of sending data through a serial RS-232 port) are coming. Even more, a new concept of Laboratory-as-a-Service in which a full experiment can be designed online in a web interface and then molecular and bacterial dynamics can be studied automatically for weeks by robots that take samples from a pool, put them into appropriate cloud-connected devices and record the results. A full report is generated and sent to the user as soon as the experiment finishes. Seamplex designed and implemented the devices firmware (based on Raspberry Pi and Arduino) and the network protocols (HTTPS with TLS encryption) that these devices use to communicate with the cloud server.


Feasibility of replacing the body of a car water pump with a plastic resin

Type Modeling & calculation

Country ar Argentina
Technologies CAE

Thermal, mechanical and fatigue analysis was performed to an assembly composed of the shaft, bearings and body of a water pump for refrigeration of an internal combustion engine. Taking into account temperature-dependent properties, these studies were performed first for the original body of aluminum but also for a new plastic-resin material. Parametric studies for uncertainties in the properties of the new material were conducted. A full report was prepared.
