Description
My work focuses on the themes of grief, closure, and celebration of life. Life is a catalyst both celebration and grief. Feeling joy when a life is introduced is as common as feeling pain when a life is lost. When I lost my maternal grandmother nearly a year ago, I felt grief accompanied with guilt. I never got a chance to say goodbye since we lived so far apart, her residing in the Philippines and me residing in the United States. In order to get rid of these negative emotions, I sought closure. I attended her funeral, and now I want to celebrate her life through my artwork.
My work comes in two parts: an illustration book titled The Butanding and an illustration exhibition. The book will be published through lulu.com and made available to the public. The exhibition component will be held from March 2nd to March 6th in Gallery 100 as part of my senior exhibition Post Pre-Production with six other colleagues in the School of Art. The illustration book is a narration of a little girl and her growing friendship with a whale shark. The overarching theme of the creative project is closure with the passing away of loved ones.
The Butanding is a narrative illustration book about a young girl befriending the local menace of her village, the whale shark. Similar to my own experience, the main subject—the young girl—of my narrative is shown suffering from grief and guilt over her grandmother’s death. My work illustrates a progression of the young girl’s emotional state as she goes on a journey with the whale shark or locally known in the Philippines as the “butanding”. It provides the scenario of a grieving individual who gets the chance to reconnect with a deceased loved one and rebuild relationships that were lost.

Description
A previously developed small time scale fatigue crack growth model is improved, modified and extended with an emphasis on creating the simplest models that maintain the desired level of accuracy for a variety of materials. The model provides a means of estimating load sequence effects by continuously updating the crack opening stress every cycle, in a simplified manner. One of the significant phenomena of the crack opening stress under negative stress ratio is the residual tensile stress induced by the applied compressive stress. A modified coefficient is introduced to determine the extent to which residual stress impact the crack closure and is observed to vary for different materials. Several other literature models for crack closure under constant loading are also reviewed and compared with the proposed model. The modified model is then shown to predict several sets of published test results under constant loading for a variety of materials.
The crack opening stress is formalized as a function of the plastic zone sizes at the crack tip and the current crack length, which provided a means of approximation, accounting for both acceleration and retardation effects in a simplified manner. A sensitivity parameter is introduced to modify the enlarged plastic zone due to overload, to better fit the delay cycles with the test data and is observed to vary for different materials. Furthermore, the interaction effect induced by the combination of overload and underload sequence is modeled by depleting the compressive plastic zone due to an overload with the tensile plastic zone due to an underload. A qualitative analysis showed the simulation capacity of the small time scale model under different load types. A good agreement between prediction and test data for several irregular load types proved the applicability of the small time scale model under variable amplitude loading.
